Using this upgraded Onibi head is super easy. First, carefully remove the original head from your SH Figuarts Shinkocchou Seihou Hibiki figure and replace it with this new one. You can attach the included Onibi attack effect piece to create an awesome display of the Onibi attack. When choosing between the metallic purple and polarized purple helmets, pick the one that suits your preference. As for maintenance, keep it away from direct sunlight and excessive heat to prevent color fading. Also, handle it gently to avoid any damage to the delicate parts like the mouth and accessories. If it gets dirty, you can use a soft, dry cloth to wipe it clean.
