This is a stick-on, peelable, removable, multi-use foil, made of paper, cellophane, or suchlike material, having a ring of adhesive gum on one side, to be used as a temporary cover for the ear-piece of a telephone receiver. It may have a few small holes in the central area for ease of passage of sound to the listener's ear. It is stored singly or in stack on a relatively thicker board, using the said gum for sticking to each other in a stack or to the said storage board.
