A mobile storage system includes a cabinet convertible between an open configuration for storing items and a folded configuration for transportation of the cabinet. The cabinet includes rear, left, right, top, and bottom walls that cooperate to form an Interior storage space having a front opening. The cabinet further includes a pair of wheels and a handle so that the cabinet can be moved as a cart. One or more drawers can be removably connected to and supported by drawer slides within the cabinet so that the drawers are movable into and out of the Interior storage space through the front opening. The drawers can be configured to be used as drawers for long term storage when located within the cabinet and as suitcases for travelling storage when removed from the cabinet.
