The Grand Prix has twenty-four flexible road parts to lay-out a really cool racetrack of 151 inch length. The shape of the parts are straight and curved with special race markings on both sides including curbstones in the corners, finish line, starting grid and pit box. The high grade, child safe material is tough, unbreakable and yet flexible so that obstacles can be taken and the racetrack can be laid out on almost any surface... indoors and out! Note: the cars are not included in the set.
