This construction set promotes imaginative play: upcycle that cardboard in your recycling bin and create fantastic animals, tall buildings, or anything a child can think of. The 36 included short screws and 12 long screws fasten pieces of cardboard together. A “scru-driver,” a multi-tool, and plastic safe-saw complete the set. WARNING: Choking hazard. Contains small parts. For ages 4 and up.
