A writing instrument has multiple writing inserts to enable a user to write with more than one color. The inserts are mounted into a body having a generally oblong cross-section with at least two tips extending from one end of the body. The body dimensions create a pair of flat, opposed gripping surfaces which enable the user to index the movement from one tip to the other using only one hand and no moving parts, while positioning the tips a far enough distance apart to ensure that only one tip at a time contacts the writing surface.
