Abstract: A storage container system of stackable containers for storage and transport of assembleable toys or puzzles. The device features a container with hinged first and second halves forming an interior cavity when releasably engaged. Each container has a plurality of projections extending from one exterior surface adapted for cooperative frictional engagement into the recesses in the opposite side of a similar sized container stacked upon it. In addition to storage, the containers provide depictions of the stored toy allowing identification by non-reading children, and an organized working surface for toy assembly.
