Abstract of the Disclosure A cosmetic applicator for moldable soft materials which permits the ready formation of a fine point. The body of the applicator has a chamber in which a charge of such soft material is positioned. A piston co-operable with the body acts directly on the charge to force it out the open front end of the chamber into a cap having an interior conical surface. The conical surface and the interior surface of the chamber are sufficiently smooth and non-sticking so that the charge of moldable material is freely slidable within the chamber and readily releasable from the conical surface.
