The Sharper Image Demolition Car Pack provides high-octane fun for you and a friend. Choose your derby car and use the dual joystick wireless remote to battle each other until one car remains intact and your opponent is blown to pieces! The fun does not have to stop when the panels come off. Use the built-in functional body panels to become your own mechanic and piece it back together more racing! The steering remote controller comes equipped with two ways to control the sports car. Recommended for 5 years and up. Requires 3 AAA for the each car and 2 AA batteries for each remote control (not included).
