Legacy board games changed everything for our group. When we cracked open Pandemic Legacy: Season 1 for the first time, we knew those cards were going to get stickers, scribbles, and tears over the next 12 to 24 sessions. That realization hit our wallet hard. We needed to figure out how to sleeve a legacy game the right way, before we started destroying the components.
Most guides stop at “buy sleeves and put cards in them.” That advice falls apart when you’re dealing with campaigns like Gloomhaven, Charterstone, or Kingdom Legacy, where permanent marker on sleeves becomes part of the play experience. After sleeving roughly 4,500 cards across 11 different legacy campaigns, our team learned what works, what bleeds, and what makes a game replayable when the campaign ends.
This guide covers everything we wish someone had told us on day one: which sleeves actually accept marker ink, which ones ghost your writing, how to prep an entire game before session one, and how to make your campaign replayable months later. Whether you’re protecting a $100 investment or just want your stickers to peel off cleanly, this walkthrough covers the full process.

What Is Sleeving and Why Legacy Games Need Special Protection?
Sleeving means sliding each card into a thin plastic cover that protects it from wear, moisture, skin oils, and accidental damage. For most board games, sleeving is an optional layer of protection. For legacy games, it’s almost mandatory because of how those campaigns treat cards.
Legacy games actively modify components. You’ll peel stickers, scribble notes, tear cards, and sometimes destroy pieces. The game expects this damage as part of the storytelling. Without sleeves, your $75 to $130 investment becomes a one-and-done playthrough with destroyed cardboard. With the right sleeves, those cards survive as a complete campaign you can revisit, lend out, or even replay with fresh modifications.
The protection matters even before you start marking things. Sticky fingers from snacks, mid-game drinks, shuffling damage, and edge whitening from frequent handling all degrade cards between sessions. Sleeves act as a sacrificial layer that takes the abuse so the original cards don’t have to.
Types of Card Sleeves Explained
Four main sleeve types show up in the board game world. Each behaves differently when you start drawing on them with markers.
Standard Card Sleeves
Standard sleeves run roughly 1 to 2mm larger than the card itself in each dimension. This extra space (called “buffer”) makes them easy to slide cards in and out. The buffer also makes them easier to shuffle because there’s some give between cards. For legacy games, standard sleeves give you room to write on the sleeve surface without the ink bleeding onto the card underneath.
Perfect Fit Sleeves
Perfect fit sleeves hug the card tightly with almost no extra space. Card flippers and tournament TCG players love them because the card feels almost bare. For legacy games, they create a problem: you can’t easily slide a card out to write on it, and the sleeve sits so close that marker ink can transfer directly to the card face.
Penny Sleeves
Penny sleeves are the cheapest, thinnest option available. They’re typically 30 to 40 microns thick and sold in huge packs for very little money. They work as backup protection but tear easily and rarely hold marker ink well. Most legacy players skip penny sleeves for the campaign deck but use them for non-marked components like location tiles or reference cards.
Premium Sleeves (Dragon Shield, Ultimate Guard, Gamegenic)
Premium sleeves combine thicker material (90 to 120 microns), better shuffle feel, and consistent sizing. For legacy games, premium clear or matte sleeves give the most reliable writing surface. They cost more, but when you’re protecting cards you’ll spend 20+ hours playing with, the extra $15 to $30 for a full game is worth it.
Card Sleeve Materials and Thickness Guide
Sleeve material affects how markers sit on the surface, how long the sleeve lasts, and whether the plastic reacts with ink over time.
Polypropylene (PP)
Polypropylene is the industry standard. It’s archival-safe, doesn’t contain plasticizers that degrade ink, and accepts most permanent markers without bleeding. Most Dragon Shield, Ultimate Guard, and Mayday sleeves use PP. For legacy games, PP is the safest choice because marker ink dries cleanly and won’t smear weeks later.
PVC Sleeves
PVC sleeves used to be common but have largely been phased out for board games. PVC contains plasticizers that can break down over time, turning sleeves cloudy or sticky. They also tend to reject certain marker inks, causing ink to bead up rather than dry flat. Avoid PVC for legacy games where you’ll be storing marked cards for years.
OPP (Oriented Polypropylene)
OPP is a stiffer variant of PP used in some ultra-thin sleeves. It’s archival-safe and very clear. The trade-off is a slightly stiffer shuffle feel. OPP sleeves accept marker ink well, though some thin varieties let ink show through to the card underneath.
Thickness (Microns)
Micron thickness matters more for legacy games than for standard play. Thin sleeves (40 to 60 microns) are cheaper but allow marker ink to show through to the card. Mid-thickness sleeves (75 to 90 microns) balance cost and protection well. Thick sleeves (100+ microns) feel premium and hold ink on the surface without bleed-through, but cost more and make boxed games harder to close.
For most legacy campaigns, 90 micron sleeves hit the sweet spot: durable enough to resist tearing during handling, thick enough to keep ink on the surface, shuffleable, and reasonably priced.
How to Sleeve a Legacy Game Step-by-Step?
This is the process our team uses before cracking any new legacy game. Following these steps takes 1 to 3 hours depending on card count but saves headaches for the next 12 to 24 sessions.
Step 1: Inventory and Sort All Cards
Empty the box. Separate cards by size and type. Legacy games often ship with 3 to 5 different card sizes: standard poker size, mini-European size, square tarot size, and oversized cards. Sorting first prevents accidentally putting a tarot-sized card into a poker-sized sleeve halfway through.
Step 2: Measure and Match Sleeve Sizes
Measure a representative card from each pile with a ruler (length x width in millimeters). Match each size to a sleeve. Most sleeve brands print the card dimensions on the package, or list them on the product page. If you’re between sizes, go up. A sleeve that’s 1mm too big is fine. A sleeve that’s 1mm too small will deform the card.
Step 3: Pick the Right Sleeve Type
For cards you’ll mark on, choose clear or matte transparent sleeves 75 to 100 microns thick. For cards that stay unmarked (event decks, secret objectives), either clear or opaque backs work. Many legacy players use opaque backs on marked cards to hide wear patterns that would otherwise telegraph card identity mid-shuffle.
Step 4: Sleeve All Cards Before Session One
This is the step most players skip. Sleeve every card before the first session so you don’t run into “which version of this card did I already mark” confusion mid-campaign. Set up on a flat, clean surface with good lighting and work in batches of 20 to 50 cards.
Step 5: Test the Shuffle Feel
Once a sample of cards is sleeved, shuffle the deck 10 to 15 times. If the cards feel sloppy, hard to riffle, or catch on each other, the sleeves are too tight or too loose. Adjust by trying a different brand or size before committing to the full pack.
Step 6: Pre-Mark Staging Areas
Some legacy games (Gloomhaven, Frosthaven) include blank sticker sheets or damage tokens. Before sealing the box, set up a “campaign tray” with your permanent markers, a clean cloth, and spare sleeves. Keeping marking supplies with the game means you’ll actually use them mid-session instead of saying “I’ll grab a pen next time.”
How to Sleeve Cards Without Damaging Them?
Sleeving looks simple but it’s easy to damage cards if you rush. We learned this the hard way by creasing card corners while forcing them into tight sleeves.
Always work on a flat surface. A dining table with a clean cloth works better than a couch or carpet. Hold the sleeve open with one hand, slide the card in at a slight angle with the other, then flatten. Don’t force. If the card resists, the sleeve is too small, or the card is misaligned.
Watch for dust and static. Plastic sleeves attract lint. Run a clean, dry cloth over each card before sleeving, especially after sorting. Static can cause sleeves to cling to each other in the box, making setup annoying. A quick swipe with a dryer sheet on the outside of the sleeve reduces static cling.
Don’t over-bend sleeves when riffling. Some premium sleeves (especially 100+ micron variants) feel stiff on first shuffle. They break in after 10 to 20 shuffles. Don’t assume they’re too tight if the first shuffle feels hard.
Avoid cutting sleeves to fit. If a sleeve is wrong, replace it. Cutting opens up the seam and defeats the entire purpose of protection.
Keep sleeves away from heat during the sleeving process. Direct sunlight on a hot sleeve can warp it slightly, causing misfit later. Work indoors at room temperature.
Writing on Sleeves: The Marker Guide for Legacy Games
This is the section most legacy game guides skip. Marker choice matters as much as sleeve choice.
Permanent Markers (Sharpie, Staedtler Lumocolor)
Permanent markers are the workhorse for legacy marking. Black Sharpies work on both matte and clear PP sleeves, dry in 10 to 30 seconds, and rarely smear once dry. The downside: ink cannot be removed without alcohol or acetone, which can also damage the sleeve surface. Use permanent markers when you genuinely want to mark something forever, like permanent upgrades or destroyed component rules.
Wet-Erase Markers
Wet-erase markers (also called “whiteboard markers”) use ink that bonds to the surface but can be wiped off with a damp cloth. These are perfect for campaigns you might want to replay. Many players use wet-erase for kingdom building in Charterstone or for tracking variable setup in Kingdom Legacy. Ink removal takes 20 to 30 seconds of gentle wiping and doesn’t damage the sleeve.
Dry-Erase Markers
Dry-erase markers look similar to wet-erase but wipe off with any dry cloth. They’re the most reusable option but also the most fragile. Dry-erase ink can smear mid-game if a damp finger touches the card. Reserve dry-erase for components handled carefully (like campaign trackers that don’t get shuffled).
Best Markers for Different Sleeve Types
On matte sleeves, both Sharpies and wet-erase markers work well. The textured surface grips ink well and minimizes smearing. On clear glossy sleeves, Sharpie ink tends to sit on the surface for a moment before drying. Give it 30 seconds before handling to avoid smudges.
Avoid ballpoint pens and standard gel pens. They don’t dry on plastic and will smear for weeks. If you want fine lines, use a fine-tip Sharpie or a paint pen designed for plastic surfaces.
Test any marker on a spare sleeve before committing. Write a test dot, let it dry 60 seconds, then try to wipe it off with a dry cloth, then a damp cloth. This 2-minute test tells you everything you need to know.
Sleeve Size Guide for Popular Legacy Games
These are the most-searched sleeve sizes for popular legacy titles. Use them as a starting point, but always measure your actual cards because print runs occasionally vary.
Pandemic Legacy: Season 1 and Season 2 use standard poker-size cards (63 x 88mm). Most “premium” sleeves labeled “board game” fit these.
Gloomhaven and Frosthaven use multiple sizes. Character ability cards are 41 x 63mm (mini-European), while attack modifier and event cards are 63 x 88mm. You’ll need two sleeve sizes for a complete job.
Charterstone uses standard poker-size cards plus a few smaller reference cards. Most players sleeve just the action cards and leave the rule reference cards bare.
Kingdom Legacy and Sleeping Gods use tarot-sized cards (70 x 120mm). Tarot sleeves fit these. Both campaigns benefit hugely from wet-erase markers because players often rewrite or change marks.
Risk Legacy and Betrayal Legacy vary by edition. Measure each batch before buying sleeves in bulk.
Storage Tips for Sleeved Legacy Game Cards
Sleeved cards take up more space than bare cards. Plan for it.
Store cards upright, in the same direction, exactly as the game instructs. Stacking sleeved cards flat can leave marker ink to transfer between cards if the ink wasn’t fully dry. Use the plastic dividers that came with the game to keep draw decks separate from discard decks.
Rubber bands work for grouping damaged card packs, but paper-clipping marker-stained cards causes the ink to transfer. Use small plastic bags or dedicated box inserts for permanent storage.
Keep markers with the game, but separate from the cards. We’ve seen ink caps come loose and stain an entire deck. A small zip bag with the markers inside, stored on top of the rulebook, keeps everything together without risk.
Check box fit before sleeving. Sleeved games often need the lid closed with foam inserts removed or the box turned sideways. Some legacy games ship with lid overhang that closes fine over thick sleeves. Others don’t fit at all and need a plano box or storage solution. Better to find out before you’ve spent two hours sleeving.
Frequently Asked Questions
Can you write on card sleeves with a Sharpie?
Yes, Sharpies work well on most polypropylene card sleeves, including clear and matte varieties. Let the ink dry for 30 seconds before handling to avoid smudging. Sharpie ink cannot be removed without alcohol, which can also damage the sleeve surface, so use Sharpie only for permanent markings.
What is the difference between perfect fit and regular card sleeves?
Perfect fit sleeves hug the card tightly with almost no extra space, giving a bare-card feel preferred by tournament players. Regular (standard) sleeves have 1 to 2mm of buffer space, making cards easier to slide in and out and providing a better surface for writing. For legacy games where you mark sleeves with markers, standard sleeves are the better choice.
How do you make a legacy game replayable?
Make a legacy game replayable by sleeving all cards before the first session, using wet-erase markers instead of stickers or permanent ink, and keeping a campaign journal of all decisions. Some games like Kingdom Legacy and Sleeping Gods were designed with replayability in mind and work especially well with this approach.
Should you sleeve cards before or after first play of a legacy game?
Sleeve cards before the first play. Once a legacy campaign starts, you’ll quickly encounter cards that get stickers, scribbles, or torn corners. Sleeving first establishes a baseline of unmarked cards and avoids mid-campaign confusion about which cards have already been modified. It also lets you decide between wet-erase and permanent markers for each card type.
What markers work best on matte vs clear sleeves?
On matte sleeves, both permanent markers (Sharpie) and wet-erase markers work well, with the textured surface gripping ink and minimizing smearing. On clear glossy sleeves, Sharpie ink tends to sit on the surface longer before drying, so give it 30 to 60 seconds of drying time before handling. Test markers on a spare sleeve before marking important cards.
Final Thoughts on Sleeving Legacy Games
Learning how to sleeve a legacy game is the single best prep step before starting a campaign. It costs $15 to $40, takes two to three hours, and protects a $75 to $130 investment across the entire playthrough. More importantly, it preserves the campaign as a complete experience you can revisit, lend out, or even replay with fresh sleeves later.
Start with transparent polypropylene sleeves in the 90 micron range. Buy one extra pack to test marker types before committing. Sleeve every card before session one. Set up your marker tray alongside the game box. These four steps cover 90% of what legacy players need.
Our team has replayed Charterstone three times and Kingdom Legacy twice because we sleeved from the start and chose wet-erase markers for the variable components. The investment paid for itself after the first campaign ended and we sold the game to a friend who hadn’t played it yet. They got a complete, undamaged experience, and we got our money back to fund the next legacy title.
