Penagain Ergosof, Ballpoint black ink Pen, Black Pen with 2 Black Refills, 1 Blue Zebra Refill. The PenAgain ergonomic design takes advantage of the weight of your hand to create the pressure needed to apply ink to paper. The unique shape encourages a natural wrist position and reduces grip related hand stress. These features make it a comfortable pen for anyone with arthritis, carpal tunnel and persons who write a lot. Whether you are right or left-handed, the PenAgain pen will prevent sore fingers, wrist pain and allow you to write comfortably longer. Along with new enhancements like a pocket clip, retractable cap, easier refilling and more streamlined ergonomics, the new Ergo-Sof PenAgain is also finished with a soft rubber coating that adds extra comfort and style. Ergo-Sof pens are individually packaged with two additional black refills.
