Using this Katsuki Bakugo action figure is easy. First, take it out of the box carefully. You can start by posing it using the movable joints. Move the arms, legs, and torso to create different dynamic poses just like in the show. If you want to recreate action scenes, attach the explosion effect parts to the figure. When it comes to the interchangeable faces, gently remove the current face and replace it with the one you like. As for maintenance, keep the figure away from direct sunlight to prevent color fading. If it gets dirty, use a soft, dry cloth to gently wipe it. Avoid using any harsh chemicals or abrasive materials as they might damage the figure. Also, when not in use, store it in a cool, dry place to keep it in good condition.
