These sleeves are perfect for the game Space Base and any other cards that are 40 X 89 MM in size. Note that they sized these for 40 X 89 cards rather than 39 X 89 so they could also accommodate Coin & Crown, another popular game that is just 1 MM wider than Space Base cards, but both of these games' cards will be well protected in these sleeves!.
