The ZOOBCube is a clever product that combines ZOOB's open-ended building with built-in storage. The thick, sturdy tiles have holes that hold ZOOB pieces and let them move, so they can be used as building platforms or part of imaginative constructions such as a tree house, an aquarium, and a suitcase. When kids are done playing, the tiles fold up to provide a storage bin. The ZOOBCube includes 90 ZOOB pieces, five 5/8" thick tiles, and 5 instruction guides.
