Using this set is easy and fun. First, you can attach the X - Unit to the Birth Driver. Then insert the Cell Medals into the slots on the driver to activate different functions, just like in the show. When handling the Cell Medals, be gentle as they are small and delicate. Keep them away from small children to avoid choking hazards. For maintenance, store the set in a cool, dry place. If the parts get dirty, you can use a soft, dry cloth to wipe them clean. Avoid using any harsh chemicals or abrasive materials as they may damage the set.
