These scream-style masks are made from a mix of molded and flexible materials, including polyester, latex, PVC (polyvinyl chloride), rubber, and various plastics.
Masks commonly have eye openings or mesh-covered eye holes for vision, and either open mouth openings or mesh in the mouth area to allow breathing while limiting visibility through the mouth.
Some masks include a mouth-mover or a hinged jaw that moves with your jaw, and others have animated or moving mouth features to create expression.
Some masks include LED light strips and require batteries. LED-style masks in this set are typically plastic and list battery requirements (for example, two AA batteries) and basic control modes such as steady or flicker.
Fit is generally handled with adult or general sizing, and some masks include internal comfort features—such as elastic straps and foam padding—to help secure a snug fit for most adults.
