Tojo-cargo is an expandable and flexible rolling container. It consists of a lower part on wheels and an upper part with a handlebar. The attachment modules can be added in any desired number between the lower and upper parts. The wheels attached to the base module and the bar installed on top facilitate the easy movement of the Tojo-cargo. Each module features a drawer compartment. When equipped with an attachment module, it fits perfectly under the desk and serves as a rolling container. In the bedroom, it can be used as a mobile nightstand. Tojo-cargo can be expanded with additional modules if more storage space is needed.
