Using this Kamen Rider Gavv transformation belt is super easy. First, open the mouth of the belt and put in a Gochizo. There's a Poppin Gummy included to get you started. Then, turn the handle and enjoy the LEDs lighting up and the cool sound effects, just like munching. If you turn the handle again, you'll trigger more LEDs and a special move sound. You can also use other items from the Rider Gochizu series, but they're sold separately. For the China release, you'll get a bonus Gochizo. The Japanese release has bonuses on a first-come, first-served basis. When it comes to maintenance, keep it away from water and rough handling. If it gets dirty, use a dry cloth to gently wipe it. And don't forget, shipping is free in the Continental USA.
