When it comes to game card sleeve sizes, here is some additional information and details:
 

1. Thickness: In addition to width and length, the thickness of the game card sleeve is also an important consideration. The thickness of game cards varies by game type and manufacturer, so the card sleeve should be thick enough to accommodate the thickness of the card and provide adequate protection. Generally speaking, the standard thickness of game card sleeves is 0.08mm to 0.12mm.
2. Transparency: Game card sleeves are usually transparent so that players can clearly see the content and patterns of the cards without taking them out. High transparency card sleeves can provide better visual effects and keep the cards readable.
3. Material: Game card sleeves are usually made of plastic materials, such as polyvinyl chloride (PVC) or polypropylene (PP). These materials are flexible and durable, effectively protecting cards from scratches and damage. In addition, some card holders are made of special materials, such as UV-resistant materials, which can prevent the cards from fading in the sun.
4. Set Quantity: Game card sets are usually sold in sets or packages. Set quantities can vary based on different brands and manufacturers, often containing 50, 100 or more card holders. This can meet the different needs of players, from individual players to professional collectors, everyone can find a suitable quantity.
5. Self-adhesive seal: Some game card sleeves have self-adhesive seals that can easily close the card
sleeve to prevent the cards from accidentally sliding out. This design is especially suitable for frequently
taking out and putting back cards, ensuring the safety and neatness of the cards.
