Across the listings, kids' Halloween masks are made from polyester, plastic, latex, and rubber.
Listings include suggested ages such as "3 years and up", "5–12 years", "5 years and up", and "6 years and up."
Common fastening methods are elastic cord ear loops, elastic bands around the back of the head, and stretchable elastic straps designed to fit most wearers.
Descriptions include faux fur coverings, foam padding for comfort and positioning, and some latex masks finished with natural alpaca hair or small hair patches for added texture.
Descriptions note stretchy features—for example, a 12-inch elastic that can stretch up to about 24 inches, or a 22" circumference listed as able to stretch to fit most wearers.
