This is the building set that lets children construct tunnels, mazes and forts in configurations limited only by their imagination. Even small hands can snap together the panels in this set to make lengths of wall or wrap-around enclosures. Each of the 46 brightly-colored rigid panels can be reinforced by joint attachment clips that secure the panels in 90° or 180° segments, ensuring that constructions remain standing during play. When it's time for demolition, the panels separate quickly, stack flat and fit neatly into the zippered carrying case. The included instruction manual includes diagrams for building 12 structures, though young architects will find many more configurations with experimentation. Made of a non-toxic polymer that is UV resistant. Ages 6 and up. 16" H x 23" W x 16" D. (29 lbs.)
