Promising review: "These are great for nursing students. I need the different colors to keep my patients' information straight. Each color is for a different patient and my system has worked very well. The colors are also more appealing than your normal four-color pen, which I like. I bought this pen over a year ago and am still on pen number one, so I can confirm they also last a very long time." —Zoomzoomxpress
