Most of the toy cars are 1:64 scale. Larger playsets and a few specialty items are often listed as Not to Scale.
Most items are made from plastic or a combination of metal and plastic. Some products are plastic-only, while others list both metal and plastic components.
These toys are generally aimed at young children. Typical recommended ages listed are “3 years and up” or “4 years and up,” depending on the specific item.
You place the coated car into the reusable drum or dunk/swish it in water to reveal a hidden design. Cold water typically reveals one look, and very warm water returns it to the original appearance. Reviewers note the effect is temperature-sensitive, so results can vary with water temperature.
Some large track sets extend several feet—for example, an 8-foot-long course in the data—and they use 1:64-scale die-cast vehicles for racing.
