Edushape wind-up cars teach physics concepts during play. Pull back the car, rile up the engine, and see the car zoom forward! Babies spend hours moving around while playing with Edushape wind-up cars. This develops fine and gross motor skills, encourages crawling & grasping while improving children's balance and coordination. Edushape wind-up cars are made of quality materials & are just the right size for baby's little hands to grip! One supplied. Order more than one to receive a variety.
