The silver robot mask is made from a vinyl exterior and a soft, yielding interior. The eyes, nose and ears are made of a shiny fabric and the antenna on top of the costume exists of black felt. The middle of the robot mask is open for comfortable breathing. The mask measures at 10” side to side and 6” front to back and fits both children and adults. This robot mask is great for anyone looking for a cool, fun costume with retro-futuristic appeal.
