Using these Hot Wheels character cars is easy. Just give them a little push and watch them roll! They're great for kids to use in pretend play and create their own stories. When it comes to storage, keep them in a dry place away from sharp objects to avoid scratches. If they get dirty, you can gently wipe them with a soft, dry cloth. Remember, the styles are randomly selected at dispatch. If you have a specific style in mind, make sure to add a note in your order. Also, each car is sold separately, so you can collect as many as you like to build your own unique collection.
