Abstract
A screw-type propel/repel lipstick has a stepped profile along one edge of the slot in the sleeve of a lipstick. The stepped edge is on the lower end of the spiral opening in the cam where the opening overlies the slot. Preferably, the cup lug has a point in its cross section pointing down toward the stepped side of the slot. When the pomade starts to backoff, the point of the lug catches on the stepped profile.
