The FleXtreme universe enables children to create a circuit by assembling the parts to each other. With Stitch FleXtreme, children can realize the most incredible circuit possible thanks to their ... creativity and the environment that surrounds them. The tracks fit easily and are so flexible that the child can move his tracks over a chair, his bed, or his dresser. But not only looping, upside down, on the side. This Stitch set is composed of 184 tracks (a circuit of 4m40), 1 luminous electronic Stitch vehicle, and a special wave fixing clamp. Batteries included.
