Using this Red Beetle LED Head is easy. First, make sure you have a CR927 battery handy as it's not included. Insert the battery into the designated slot. Then, attach the LED head to your SH Figuarts Shinkocchou Seihou Kabuto figure. You can activate the LED function by simply using the magnetic control. When it comes to choosing a color, pick the metallic red if you have the old - version figure, or the bright metallic red for the 10th anniversary edition. Keep in mind that the figure is sold separately. For maintenance, avoid getting the LED head wet. Store it in a cool, dry place when not in use. This will help keep the LED function working well and preserve the overall quality of the head.
