An exciting, interactive wood product for a youngster's playroom or even an executive office. Marbles make their way through a maze of switches and diverters directing marbles over a xylophone, around a spiral, through a zig-zag trail, a springboard, and six other marble activated devices. The chest is the size of a large tool box. It closes and locks for easy transport. A great heirloom for your family. Finished size: 26" W, 13" D, & 26" H.
