Marcus Square Card Sleeves are custom-designed for smaller square cards measuring 65×65 mm, making them the perfect choice for protecting mini board game components, abstract game cards, and special expansion decks. Whether you’re sleeving collectible inserts or high-usage play cards, these sleeves provide a perfect balance of clarity, durability, and a precise fit.
Built to Last – Compact Protection That Performs
Manufactured using 90-micron premium film, Marcus sleeves stand up to regular use, shuffling, and game table wear while maintaining a smooth, flexible profile. Each pack includes 55 sleeves, so you’ll always have enough — even if you lose or damage a few during setup or play.
High Clarity & Archival Safety
Show off your card artwork with crystal-clear film that doesn’t cloud or distort. These sleeves are acid-free and PVC-free, which means your cards are safe from discoloration or chemical degradation, even after long-term storage.
