ABSTRACT:
A stack of face masks is disclosed. The stack is formed from a plurality of shaped face masks having an inside surface and an outside surface. The inside surface includes a periphery with an adhesive material disposed on at least a portion thereof. The masks are positioned in a nestled relation to one another, the inside surface of the mask being apposed to the outside surface of an adjacent mask, thereby forming a stack. The masks are adapted to maintain a distance between apposed masks so that the periphery of a mask does not contact the outside surface of an apposed mask.
