Using this Figure Rise model is a lot of fun. First, carefully take out all the parts from the kit. Then, follow the included instructions to assemble the model piece by piece. Be gentle when handling the small parts like the clear eyes and the additional hands to avoid breakage. When attaching the Drill Crusher, make sure it's properly aligned so it can transform smoothly. As for maintenance, keep the model away from direct sunlight and moisture to prevent any damage to the colors and materials. Also, if you're not displaying it, store it in a cool, dry place. Have a great time building and showing off your Kamen Rider Build Rabbit Tank Form model!
