Using these cool DX Arc Cubes is super easy. First, make sure you have the DX Arc Riser (sold separately). Then, just insert the cubes into the riser to hear the exciting dialogue and BGM from the show. When you're done using them, store the cubes in a dry and safe place to keep them in good condition. Avoid dropping or hitting the cubes hard as it might damage them. Also, don't expose them to extreme temperatures. If you want to clean them, use a soft, dry cloth. Have fun with your Ultraman Arc Cube set!
