Plastic costume masks are commonly made from general plastics and specific types such as PVC, ABS, and polyethylene.
Light-up and electronic plastic masks use various battery types: some require AA batteries (one or multiple), some use AAA batteries, and others list no battery needed.
Some plastic costume masks include play features such as multi‑mode LED lighting, flip‑up light effects, voice‑changing electronics, sounds, and mist effects for role play.
Many masks use adjustable elastic or adjustable straps to secure the mask and help fit different head shapes and sizes.
Suggested ages vary; examples found in listings include: 1 Year and Up, 4 Years and Up, 5 Years and Up, 8 Years and Up, and some items listed as All Ages.
Common options include separate eye openings or mouth openings; some masks list combined eye/mouth/nose openings, while others are described as having no openings.
