Using these Monster Jam trucks is super easy! Just grab the two trucks from the 2 - Pack and start creating your own Monster Jam battles. You can race them on flat surfaces or create obstacle courses. For the best play experience, make sure the surface is clean and smooth. When it comes to maintenance, keep the trucks away from water and rough play that could damage the details or graphics. If they get dirty, you can use a soft, dry cloth to gently wipe them clean. Remember, these trucks are for kids 3 and up, so adult supervision is recommended to avoid any small parts being swallowed.
