Serial killers are widely feared due to their twisted imagination. Take our serial killer Otis, for example. Sewing his mouth shut like a baseball glove is one thing, but enlarging it with a kitchen knife beforehand is another. And the lines around his eyes clearly mark the strike zone. How fitting! The wounds on this latex mask are modeled in authentic bas-relief, and the realistic airbrush work gives serial killer Otis a disturbingly lifelike face. An elastic band keeps the half mask in place over your own face. It has nostrils for easier breathing, and the mouth opening allows you to drink through a straw. And all of this without any pain!.
