Using this Hot Wheels set is super easy. Just take the cars out of the window package and start playing or display them in your collection. Remember, these are collectible items, so handle them gently to avoid any scratches. To keep them looking great, you can use a soft, dry cloth to wipe off any dust. Also, store them in a cool, dry place away from direct sunlight to prevent the colors from fading. Each set is sold separately, so if you want to collect them all, keep an eye on the availability.
