Abstract

See full text

A writing instrument includes an elongated body housing a spool valve and a writing tip secured to a distal end of the elongated body. Two or more fluid reservoirs in selective fluid communication with the writing tip. Axial movement of the spool valve relative to the elongated body of the writing instrument alternately establishes fluid flow paths between the fluid reservoirs and the writing tip.
