ABSTRACT:
A multi-element writing instrument is disclosed wherein the rotation of a selection portion located at one end of the instrument successively selects, advances and retracts individual writing elements. The writing point of each selected writing element is axially advanced through the exit opening without contact with the interior of the body of the instrument. In the writing position the axis of the selected element is aligned with the axis of the instrument. The novel construction permits the use of elements that employ different types of nibs, for example porous writing points, either alone or in combination with ball point-tipped elements.
