Magic masks generally have similar traits. They are made of a magical silky fabric that molds to the face of the person putting one on. The mask clings to the face under its own power and requires no string to hold it in place. Touching the mask allows it to be taken off. 1 in 20 masks have a stronger bond and will only come off if willed by the wearer.
Note: The Beast Masks come in a variety of different animals.
