Using this product is a breeze. First, open the mouth of the Kamen Rider Gavv transformation belt. Then, take one of the included Gochizos, like Poppin Gummy or Vrocan, and insert it. Turn the handle, and you'll get cool LEDs and sound effects. If you turn the handle again, you'll hear a special move sound. Keep your Gochizos organized in the provided Holder. When it comes to the campaign bonuses, the China release always has the bonus Gochizo, while the Japanese one offers bonuses as long as supplies last. For shipping, it's free if you're in the Continental USA. As for maintenance, keep the belt and Gochizos away from water and extreme temperatures. Don't force the handle too hard to avoid damage. Enjoy your Kamen Rider experience!
