Using this set is a breeze. First, you'll need to have the DX Zero One Driver (it's sold separately). Attach the Zero-Three Driver Unit to it, and you'll hear cool standby sounds. Next, authorize the Zero-Three Progressive Key and insert it into the belt - that's when the magic happens and you transform into Kamen Rider Zero-Three. Once you're transformed, have some fun! Press the progressive key to hear dialogues from the show. Press it twice to trigger a special move. As for maintenance, keep it away from water and extreme heat. Store it in a dry place when not in use. And remember, it's for entertainment purposes, so handle it with care to make sure it lasts a long time and keeps providing you with hours of Kamen Rider fun.
