This is a steampunk-style menpo or samurai half-mask. It comes with teeth and rivets, adding a touch of edgy and unique style.

Using this mask is easy. Just put it on your face and adjust it to fit comfortably. When using it, make sure it doesn't block your vision or breathing. After use, keep it in a dry and clean place. You can use a soft cloth to wipe it gently to keep it looking good. Don't expose it to sharp objects to avoid scratching the mask.
