With Hot Wheels® Split Speeders, kids create their own unique vehicles. In seconds, the cars split apart and reassemble! Each car has a magnet that allows it to split in two and then join with another piece to create new unique vehicles. The Split Speeders include vehicles with many different themes so kids can make their own combinations before sending them racing on the track. The special Split Speeders tracks (sold separately) are perfect for these crazy vehicles! Super collection! Not for use with some Hot Wheels® sets.
