An expandable and collapsible belt-strap container for conveniently carrying sports cards on a person comprises a container (10) having an inner side attached to the mid-portion (14) of a belt (12) by elastic webbings (13 and 13'). The container comprises an expandable and collapsible bellows (11) with an open top, and a flap (18) hingeably attached to an outer side of the container. The flap stretches across the open top and down the inner side of the bellows. A long piece of hook-and-loop fastener (19) is attached to the inner side of the bellows, while a short piece of hook-and-loop fastener (20) is attached to the distal side of the flap. Therefore, when the bellows is fully collapsed, the distal side of the flap may be attached to the lower side of the long fastener. When the bellows is fully expanded for carrying a large number of sports cards, the side of the flap may be attached to the upper side of the long fastener. Because the flap is attached to the bottom of the inner side of the container, it will stay in an opened position when swung outwardly. The bellows comprises a plurality of pleats, each having long and short sections, and sides and a bottom which are attached by curved comers, such that each pleat will be bistable (expanded or collapsed). The container, covering flap, and belt can all be separated or attached together.
