This eye-catching vehicle set is designed with the youngest builders in mind! The colorful, oversize, easy-grip pieces allow children to create an assortment of vehicles—a fire engine, a SWAT car and an ambulance. Or kids can mix & match the pieces to invent their own vehicles! The magnetic locking system makes assembly and disassembly a snap, so it’s easy to build over and over again—for a frustration-free way to develop fine motor skills. Set includes 6 truck body parts, plus chassis with real-rolling rubber tires; chassis measures 5" in length.
