A totally new effect which is revolutionizing masks! You get a white mask with red string that criss crosses the eyes and makes the mouth look like it is sewn shut but thanks to 2 AA batteries, when you get in the dark, the string lights up adding a eerie glow to the mask unlike anything you've seen before. One mask. Batteries are included. Light Up EL String. Adult Size PVC Mask with Battery Pack. Colors Green & Red.
