Speed through new horizons with the GeoSmart RoboRacer. This 36-piece magnetic construction set features multiple different geometric shapes and wheels... you can build your own Racer and watch it go! GeoSmart was conceived and designed with safety in mind. GeoSmart pieces feature a new, patented safety system. Magnets are contained within a double-welded inner core, locked in place by stainless steel caps. Covering this inner core is high-quality polycarbonate housing. The end result is pieces that are not only strong and bright, but extremely safe and durable.
