These highlighters feature lightfast, smear-proof , fade-resistant pigment ink that dries quickly and is safe for use on faxes, photocopies, and carbon copies. The special formula will not smear inkjet printouts, and the Violet and Turquoise colors allow text and highlights to remain visible on photocopies. Highlighters have a wear-resistant chisel tip and a snap-lock cap with a pocket clip. The flat barrel allows for a good grip.
