Abstract
A writing implement with three or more non-coaxial optionally selectable writing tips to produce lines of different thicknesses and to create unique and distinct "outlining" or "highlighting" effects. It is particularly adapted to be used on fibrous or felt tip type highlighter markers, but could be used on a variety of writing implements. The Meriting implement is comprised of a hollow low body supporting a fixed writing tip, a reservoir in the body holding a supply of ink, a series of two or more retractable tips slidably arranged alongside the fixed tip and adjusting means attached to each retractable tip to axially move each retracting tip to first and second operating positions, so that when moved to and locked in the first operative position, each retractable tip is extended with respect to the fixed tip, and when moved to and locked in the second operative position, each retractable tip is retracted with respect to the fixed tip. All tips are made of a porous material having capillary channels and being in fluid communication with the ink reservoir.
