Using these Hot Wheels Monster Trucks is easy. Just grab them and let them roll on any flat surface. You can also use them to stage your own monster truck shows at home. When playing, make sure to keep them away from small children who might put them in their mouths. To maintain these trucks, you can use a dry cloth to wipe off any dust or dirt. Don't expose them to water or extreme temperatures as this may damage the die - cast material and the paint. Have fun with your Hot Wheels Monster Trucks!
