This pen is great for those who work outdoors in the cold, heat, and wet weather. When conventional ball point pens fail in freezing temps, this pen exceeds the expectations. Also, if you write in the rain, it doesnt stop writing even though the paper is wet. Furthermore, this pen with the metal clip is great for those who keep it clipped to a shirt pocket and in different weather as the plastic clips of some of the other pens degrades over time. Everyone at work notices in the winter weather when their pen fails and my pen still works. I recommend this pen as a high quality, outlasting pen that even my coworkers even request.
