Using this SHF Upgrade Hyper Beetle LED Head is easy. First, make sure you have a CR927 battery on hand as it's needed to power the LED function but is not included. Simply insert the battery into the designated slot. Then, attach the head to your SH Figuarts Hyper Kabuto figure. Whether it's the old or new version, it will fit perfectly. When you want to see the LED in action, use the magnetic control. As for maintenance, keep it away from water and excessive heat. If it gets dirty, you can gently wipe it with a soft, dry cloth. Be careful when handling it to avoid any damage to the delicate parts like the compound eyes and the LED mechanism.
