Materials listed include fiberglass, metal, plastic and ABS (Acrylonitrile Butadiene Styrene). Some replicas combine metal with plastic or fiberglass, while many roleplay masks are made from ABS plastic.
Fit varies by model: some roleplay masks are sized for younger children with maximum head-size listings (for example 8 or 11 inches), while others are described as fitting most head sizes and include an adjustable strap for a secure fit.
Some masks include electronic features such as a voice-changing function and require batteries (one listing specifies 3 AA alkaline). Other replicas are non-electronic and list no battery use.
Display-ready life-size replicas may include a display base with a mannequin head; some collector replicas also include a certificate of authenticity.
Life-size replicas are described as 1:1 scale with accurate two-piece construction and are built from higher-end materials such as fiberglass, metal and plastic or ABS with metal details.
