Using this LED head is easy. First, remove the original head of your SH Figuarts Kamen Rider Tycoon Bujin. Then, simply attach this SHFU Black General LED head in its place. To turn on the LED behind the eyes, use the magnet to activate it. When you want to turn it off, use the magnet again. You can also switch between different looks by using the replacement compound eye parts included. Remember, the batteries are not included, so you'll need to get them separately. Keep the head in a dry and clean place to maintain its quality. Avoid dropping or hitting it, as this could damage the LED or other parts.
