These sleeves are GREAT for games with a lot of cards that stack. Mayday have play tested a few thicknesses and this thickness works best if you have over about 60 cards in a pile. Any thicker and they simply fall over and difficult to shuffle due to the thickness.

These are designed for cards of 41 MM X 63 MM, or 1 5/8 X 2 1/2 inches. They are 100 per pack and priced for bulk purchasing.

Examples of games with cards that this sleeve will fit: Arkham Horror, Twilight Imperium, World of Warcraft: The Board Game, Red November, and Cave Troll.
