Abstract
A retractable eraser has an elongated contoured housing which has a longitudinal slot and spaced detents and an opening at one end. A carrier has a button which is depressible so that a catch clears the detents to permit selective longitudinal displacement of the carrier. An oval shaped eraser element is mounted to the carrier and displaced into and out of the housing so as, in one position, to project beyond the housing. Bristles project longitudinally from the housing around the opening.
