T. rex masks in this selection are commonly made from plastic, latex, or polyester.
Some masks combine LED eye effects with sound. In these models the LEDs blink and sound effects trigger as the wearer opens the jaw wider; sounds can range from soft growls to progressively louder roars and some include a quick “scare” roar when the jaw snaps open.
Available masks list suggested ages from about 3 years through adult. Listed maximum head sizes in this group vary by model, roughly ranging from about 7 inches up to 26 inches depending on the mask.
Depending on the style, masks provide eye openings, mouth openings, or full-face openings to allow vision and airflow.
Some masks include an adjustable strap at the back for a snug, secure fit, and they use eye and mouth openings to improve comfort and wearability.
Inflatable heads include an attached fan and are powered by a battery pack. Some listings specify a required 4 AA battery pack (sold separately).
Hand wash the mask in cold water with mild soap, then hang it or lay it flat to dry.
Child costumes are grouped by size—examples include Toddler (3–4 years), Small (5–7 years), and Medium (8–10 years)—and often come as jumpsuit-style sets with attached feet, a tail, and a hood.
Some masks in this set require batteries—for example, 3 AAA or 4 AA—while other masks list no battery requirement.
