Simple enough for even the youngest mechanics, this delightful kit allows kids to build a motorcycle, a race car and an airplane—then play with them! Children simply screw the chunky pieces together, then push the vehicles on real-rolling wheels. Plus, the two-way electric screwdriver makes it a snap to screw in the bolts and screw them out again for nonstop building fun! Made of sturdy plastic; motorcycle measures 6". Screwdriver requires 2 “AA” batteries, not included.
