The Hot Wheels Color Shifters set includes two 1:64 scale vehicles that transform when exposed to water. When submerged in cold water, the car's color and deco completely change; warm water reverses the effect, allowing for repeated transformations. The cars feature authentic styling and detailed designs. Compatible with Hot Wheels tracks, these color-changing vehicles can be raced in multiple appearances. Designed for children ages 3 and up, these collectible cars are sold separately.
