Calling all mechanics! The Hape Build 'N' Drive Car Set is standing by! Get your hands on the wrench and screwdriver to start working on the chassis. Use the nuts and bolts to attach the wheels and give the car a test drive. This car set includes the building instructions for five different cars. Of course, children can use their imaginations to create their own designs, too. Made of wood and plastic parts, this toy is safe for children ages three and older.
