therizinosaurus mask

Listings show Therizinosaurus masks are made from plastic, while some costume hoods and related costume pieces are made from polyester.

Listings show suggested ages such as “3 Years and Up,” “5 Years and Up,” and “6 Years and Up.”

Some listings describe LED or light-up eye effects and built-in growl/roar sounds; a few note multiple increasing light-and-sound levels triggered when the jaw is opened.

Some masks require 3 AAA alkaline batteries (required but not included), while other listings specify that no battery is used.

Listings commonly mention eye and mouth openings for visibility and breathability, and adjustable straps or a rear adjustment to help secure the mask.

Mask-only listings include just the single mask piece; full costume listings may include a jumpsuit with attached feet, tail and hood and sometimes extras such as a plush egg.

Some listings include CPSC choking-hazard warnings for small parts, and some costume listings note they meet U.S. toy safety standards and have undergone safety testing.

Customer reviews commonly say the masks are fun and visually striking, praise the illumination and overall appearance, and some specifically call out the built-in sounds and lighting as positives.
