The Hot Wheels Track Builder System offers the ultimate track experience for boys by allowing them to design, create and customize their very own track challenges. Using a variety of stunts, layouts and essential pieces that work together or connect to existing sets, boys can be the master of their own track. This launch pack includes a non-motorized kicker, straight track pieces and a pullback launcher for dynamic racing options. If you can dream it, you can build it with Track Builder! Not for use with some Hot Wheels vehicles. Ages 3 and older.
