Gamegenic Just Sleeves — Standard 66×91 mm, White, Pack of 50 are protective card sleeves designed for collectible and tabletop game cards. Sized at 66×91 mm, these sleeves fit standard-sized trading cards and many board game cards, offering a balance between protection and playability. The white-backed sleeves provide a neutral appearance for deck building, storage and tournaments, while the clear front preserves card visibility and readability.

Advantages

These Gamegenic Just Sleeves combine a smooth shuffle feel with thin but durable material that helps prevent edge wear, surface scratches and minor liquid exposure. The white backing creates a uniform look for faces-down cards and can help conceal card backs for tournament play. The pack of 50 is convenient for small decks or partial upgrades and is lightweight for easy storage or transport.

Suitable for

• Standard-sized trading cards (66×91 mm)
• Board game cards and components of similar dimensions
• Deck building, casual play and small tournament decks
• Short-term storage and transportation of card decks

When it may not be suitable

These sleeves are intended for standard 66×91 mm cards; oversized or miniature cards will not fit properly. For players who require ultra-thick, archival-grade protection or waterproofing for long-term storage, these thin sleeves may not provide sufficient barrier against heavy handling or prolonged exposure to moisture.

Key specifications

• Dimensions: 66 × 91 mm (internal sleeve size suitable for standard cards)
• Color: white back with clear front
• Quantity: 50 sleeves per pack
• Material: thin, shuffle-friendly polymer film
• Finish: smooth front for readability and easy shuffling

How to use

Insert each card gently into the sleeve so that the card sits fully inside without bending. For optimal protection, align the card with the sleeve opening at the top and avoid forcing cards into sleeves that are already tightly occupied. When shuffling, consider using card shufflers or gentle riffle techniques to reduce wear. Store sleeved decks flat or upright in a box to prevent warping.

What to consider before purchase

• Verify your card dimensions are standard 66×91 mm to ensure proper fit
• Decide if white-backed sleeves suit your tournament or deck-identification needs
• Assess whether a pack of 50 covers your deck size or if bulk packs are needed
• Consider if thicker or archival sleeves are required for long-term preservation

Usage recommendations

For everyday play and casual tournaments, use these sleeves for full decks or as top-layer protection and replace sleeves showing signs of fraying. Keep sleeved decks away from prolonged sunlight and high humidity to maintain material integrity and shuffle feel.
