Using these Hot Wheels Monster Trucks is super easy! Just grab a truck and start pushing it on a flat surface to watch it zoom. You can stage exciting crash - and - smash battles with all four trucks in the pack. When it comes to storage, keep them in a dry place to prevent any damage to the paint or the wheels. Be careful not to drop them from high places as it might break the trucks. If they get dirty, you can use a soft, dry cloth to gently wipe them clean. Have a blast playing with your Hot Wheels Monster Trucks!
