Using the set is easy! First, activate the Arc Cube by pressing its button. Then, insert the activated cube into the Arc Riser. Rotate the parts of the Riser until the pattern matches to start the transformation sounds. You can have fun switching the Arc Cube between Arc Cube Mode for transformation and Sound Mode to listen to show sounds. When handling the Arc Eye Sword, be careful not to drop it as it has LEDs in the blade. Keep the set in a dry place and away from direct sunlight to maintain its quality. If the batteries run out, replace them following the instructions on the product. Enjoy your Ultraman adventures with this great set!
