To use this product, simply take your SH Figuarts Ultraman Arc action figure and attach the Galaxy Armor pieces to give it the Galaxy form. When handling the accessories like the optional hand parts, be gentle to avoid breakage. Store the set in a cool, dry place away from direct sunlight to prevent any color fading or damage. If the armor gets dirty, you can use a soft, dry cloth to gently wipe it clean. Remember, the Ultraman Arc figure is sold separately, so make sure you have it before trying to use this armor set.
