This is a damage deck holder for Star Wars: X-Wing Miniatures. It holds all 33 cards and is intended for cards sleeved in the Fantasy Flight Yellow sleeves. Unsleeved cards will fit, but not as snuggly and may slip through the cutout in the bottom. There are indentations on all four sides allowing easy removal of even the last card without having to turn the holder upside down or push up the card from the bottom. Star Trek Attack Wing happens to use an essentially identical damage deck and that deck will fit just as nicely in this holder assuming the cards are in the same size sleeve.
