Listings show a range of age recommendations: "All Ages," adult sizing, and child ranges such as "4 Years and Up" and "5 Years and Up."
Many masks list openings for the eyes and/or mouth; some include both eye and mouth openings. A few specifically note small nostril or mouth openings intended to aid breathing.
Several masks offer LED or glow effects with multiple modes (steady and flashing). Power sources vary by listing — some are battery-free while others require batteries (commonly two AA or three AAA).
Coverage varies: some masks cover the entire head or full face for a complete transformation, while others are partial face masks or bands that cover only part of the head and leave areas exposed.
Listings commonly provide overall dimensions (height × width) and sometimes state a maximum head size. In these results, heights range from about 7.8" to 11.25", widths from about 6.7" to 10.16", and reported maximum head sizes range from 7" to 23".
Kids' role-play masks commonly include electronic sound effects and light effects (LED lights, pulsating or fixed modes). Some listings also mention glow-in-the-dark accents and mist or plasma-blast style visual effects, and a few offer multiple light modes.
