Using this Super Saiyan 4 Son Goku mini figurine is easy. You can mix and match the 4 optional expressions and hands to create different poses for your Goku. For the Kamehameha effect part, simply attach it to the appropriate hand to show off Goku's signature move. When handling the figurine, be gentle to avoid breaking the small parts. Keep it away from direct sunlight and high humidity to prevent any damage to the paint. If it gets dirty, you can use a soft, dry cloth to gently wipe it clean. And remember, the bonus hand parts are for the SH Figuarts Son Goku (mini) - Daima, so make sure you have the right model to use them.
