The Hasbro’s Hulk Mask features a jaw that can move up and down, enabling you to move its mouth when speaking, along with eyebrows that can arch up to make Hulk look even angrier. You manage the moving parts utilizing your chin, as with you open your mouth to get the jaw drop down and shut your mouth to bring it in place. The eyebrows are linked to the same motion systems, so they lift the same time the jaw falls in a synchronized style.
An adjustable strap behind the mask lets you put it on your face firmly, all while allowing it to match different face dimensions. Do note, this thing is made to be used by children, so it might be a tight fit on adults.
