Using this DX EVOL X Full Bottle is easy. First, make sure you have either the DX EVOL Driver or the Build Driver. Insert the full bottle into the driver, and you'll be able to transform into Kamen Rider EVOL X and hear the cool finisher sounds. When not in use, keep it in a dry and clean place to avoid damage. Don't expose it to extreme temperatures or rough handling. If it gets dirty, you can gently wipe it with a soft cloth. Remember, the drivers are sold separately, so you'll need to purchase them if you don't already have them.
