Abstract: A small plastic storage box is particularly adapted for the storage and display of trading cards and includes an open-topped container for edgewise receipt of a stack of cards and a sliding cover to close the box and enclose the cards therein. The container also includes upwardly opening slots around the side walls into which individual trading cards can be inserted edgewise and which are visible from outside the box through the transparent plastic walls. The box also includes a modular construction whereby identical boxes can be interconnected for expanded storage capability.
