Abstract
A writing instrument such as a pen having an elongated housing of an extruded plastic tube, a molded tip member which is press fit into one end of the housing, a cartridge containing a writing medium therein such as ink therein, and including a writing tip for contacting a substrate such as paper, a molded combined clip/cam member press fit into the opposite end of the housing for retaining the cartridge therein, and an extension and retraction system for positioning the cartridge in either a first position where the tip extends beyond the forward end of the tip member or in a second position where the cartridge and tip are retained within the tip member and housing. The clip/cam member preferably includes a clip for attachment to clothing or the like while the housing preferably includes a matte finish thereon. This soft finish may be achieved by sand blasting the housing or by including an outer covering of a soft feel material such as a soft plastic or elastomer. When the outer covering is included, decorative score lines may be provided therein, either circumferentially or longitudinally.
