Most ugly Halloween masks are made from molded latex or PVC (polyvinyl chloride); listings commonly describe either molded latex masks or PVC plastic masks as the primary materials.
Sizes vary by style. Example dimensions from listings include 11 in (H) x 9 in (W), 7.8 in (H) x 6.7 in (W), and 8.66 in (H) x 7.09 in (W). Maximum head sizes listed generally range from about 7.8 to 11 inches.
Age labels vary across listings: some are marked for children (for example, "3 Years and Up"), others are listed as "All Ages," and several are labeled for adults (e.g., "18 Years and Up").
Power options vary by listing: some masks state "Battery: No Battery Used," while others say "Battery: Required, Not Included" or "Battery: Optional, Not Included." Several LED/EL-wire masks specify using two AA batteries (not included).
Openings vary by mask type: many list only eye openings, while LED or PVC masks commonly include openings for the eyes, nose, and mouth to allow visibility and breathing.
