The box is designed to hold cards for various games including Dominion, Munchkin, Cards Against Humanity, Magic the Gathering, Pokemon, YuGiOh, and many more. The rows are sized to hold both sleeved and unsleeved cards. The row dividers come out and the floor of the box is removable. This will make space for either plastic deck boxes to also be stored or room for rule books or game board to sit atop your cards.
