How to use: First, make sure you have the DX Arc Riser (sold separately). Insert the DX Arc Galaxy Armor Cube into the Riser, and you'll see Ultraman Arc transform into the Galaxy - armored form. You can also use the cube in the DX Arc Sword and DX Arc Galaxy (both sold separately) for added play fun. Note: These additional items are sold separately, so you'll need to purchase them if you want to use all the features. Maintenance: Keep the cube in a dry place away from direct sunlight. If it gets dirty, use a soft, dry cloth to gently wipe it. Avoid using harsh chemicals or abrasive materials, as they could damage the cube.
