The patented line of PenAgain pens are ergonomically designed to adapt to the contour of the hand, thus alleviating stresses normally observed with a standard pen. The natural weight of the writer's hand provides sufficient pressure to apply ink to the paper. This eliminates the need to grip the pen allowing the thumb and forefinger to serve merely as guides. The PenAgain may help alleviate the symptoms of Writers Cramp, Carpal Tunnel Syndrome, Calluses, RSI, and Arthritis. The most comfortable writing instrument in the world! Proprietary Ergo-Sof rubber coating feels like soft silk. Tension free writing with "No Grip" design. Works for "Righties" and "Lefties". Retractable and refillable. Bundle of 4 Pens.
