Using this upgrade set is a breeze. First, attach the Gesr Gun Light Saber to the end of the Geartlinger. Just make sure it fits snugly. Then, apply the Gear Gun stickers to complete the awesome look. The photobooks and stickers are for display purposes. You can show them off to your friends or use them to decorate your room. When it comes to maintenance, keep the set away from water and direct sunlight to prevent damage. Also, handle the parts gently to avoid any breakage. Have fun recreating those iconic Zenkaizer Black scenes!
