Product Overview
These sleeves are perfect for the game Space Base and any other cards that are 40x89mm in size. Note that Sleeve Kings sized these for 40x89 cards rather than 39x89 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! 100% clear polypropylene, archival safe, acid free, and no PVC. 60 microns.
