To use these Vistamps, simply insert them into the Demons Driver from the Kamen Rider Revice line. When you do, you'll be able to activate special features and transform like a pro. Remember to handle the Vistamps gently to avoid any damage. Keep them away from water and extreme temperatures. If they get dirty, you can use a soft, dry cloth to clean them. That's all you need to know to have a great time with your new Vistamps!
