Custom card sleeves for use with Fireball Island: The Curse of Vul-Kar. Each sleeve features a border that looks like scorched paper without blocking the critical information on the card back in the center.
100 sleeves is enough to sleeve the base game and at least one or two expansions. If you have all the expansions, you will need two sets of sleeves, i.e., 200 total.
