These Hot Wheels cars are great for play or display. To play, just roll them on a flat surface or use them with compatible Hot Wheels tracks. Remember, they're not for use with some Hot Wheels sets, so check before you try to combine them. Keep them away from small children under 3 due to small parts. To maintain them, you can use a soft cloth to wipe off any dust. Store them in a dry place to prevent damage. Enjoy your Hot Wheels car!
