Abstract: A card box for storing cards or the like includes a tray-like rectangular box member for storing cards and movable, tiltable supports which can be inserted into a series of holes or recesses provided lengthwise and widthwise along the edges of the bottom of the box. Pins at the opposite ends of the lower edges of the supports fit into the holes so that the supports can be located in differing positions lengthwise and widthwise of the box member permitting the cards to be stored lengthwise or widthwise of the box. In a preferred form, the ratio of internal length to width of the box is substantially the same as the ratio of height to width of the largest card to be stored.
