Using these Hot Wheels cars is super easy. Just hold the car in your hand and roll it on a flat surface like a table or the floor. You can race them with your friends or create your own tracks. When it comes to storage, keep them in the provided blister card to keep them safe and for easy display. As for maintenance, a gentle wipe with a soft cloth will keep them clean. Be careful not to drop them on hard surfaces as they are small and can get damaged. Remember, these cars are recommended for ages 8 and up, so make sure younger kids use them under adult supervision.
