Using these Hot Wheels Fast & Furious themed cars is easy. You can play with them on toy tracks to recreate exciting racing scenes, or simply put them on display to show off your collection. When playing, make sure to use them on a flat and clean surface to avoid any scratches. Since they're suitable for ages 3 and up, adult supervision is recommended for younger kids. As for maintenance, you can gently wipe the cars with a soft cloth to keep them clean. Remember, each car is sold separately, and the styles are randomly selected at dispatch. If you have a specific style in mind, it's a good idea to visit your local Toyworld store.
