The Hot Wheels Color Reveal 2 Pack includes two 1:64 scale die-cast cars, each featuring two hidden deco designs. The cars are coated in a special layer that reacts to water temperature—cool water reveals one design, while warm water reverts it to the original. The reusable barrel packaging doubles as a dunk tank for easy color-changing play. Each car offers two distinct looks, effectively providing four design variations per set. The collection features different vehicle models, encouraging kids and collectors to expand their assortment (sold separately). Designed for ages 3 and up, these cars support imaginative push-and-play scenarios. The color-reveal feature adds an interactive element, allowing repeated transformation between the two deco options.
