With 35 Creatto pieces and a string of 20 LED lights, you can build a moose, beetle, dinosaur, and tree. Battery-powered lights require 2 AA batteries. Suitable for ages 6 and up. Creatto™ is a simple yet versatile building system that consists of just two primary components that can be woven together into countless 3D creations. The flexible yet durable plastic tiles interlock quickly and easily for all skill levels; no additional materials or hardware required! Each Creatto kit includes assembly instructions for four different configurations, but the possibilities are limited only by your imagination. Add strings of colored LED lights to illuminate your works of art from the inside out. What will you create?
