Using this set is easy. First, turn on the DX VS Changer to enjoy the BGM, dialogues, and bonus recording. You can use the Red Dial Fighter and Trigger Machine #1 with the Memorial VS Changer to hear the exclusive sounds. The cards are great for collectors or to play pretend. When handling the items, be gentle to avoid scratching the gloss paint. Keep the set in a dry and cool place to maintain its quality.
