Using this special set is easy. First, take out the DX Revice Driver. Then, insert the DX Rex Vistamp or the DX Grasshopper Vistamp into the driver. Once you do that, you can transform into Kamen Rider Revi or Vice just like in the show. When you're not using the set, keep it in a cool and dry place to prevent any damage. Don't expose it to direct sunlight for a long time as it might fade the colors. If the set gets dirty, you can use a soft, dry cloth to gently wipe it clean. Also, be careful when handling the Vistamps as they are small and could be easily lost.
