These Hot Wheels cars are great for play or display. For play, just hold the car and roll it on a flat surface. You can also race them with other Hot Wheels cars. When displaying, put them in the commemorative box to keep them safe. Avoid exposing the cars to extreme heat or moisture as this can damage the paint and the metal parts. To clean the cars, use a soft, dry cloth to gently wipe them. Don't use any harsh chemicals or abrasive materials, as they might scratch the cars. Keep them out of reach of small children to prevent choking hazards if any parts come loose.
