Using this set is super easy. First, take out each of the 5 vinyl machines. You can play with them individually and admire their unique sizes and shapes. When you're ready, start combining them to form the 7.1 - foot - tall robot. Just follow the natural fit of the pieces. As for maintenance, keep them away from sharp objects to avoid scratches. Also, don't expose them to direct sunlight for too long as it might fade the colors. If they get dirty, you can gently wipe them with a soft, dry cloth. Have fun with your amazing Power Raider Giant Beast set!
