Unlike conventional pens that rely on the strength of your grip, the PenAgain’s ergonomic index finder cradle takes advantage of the natural weight of the hand to generate the pressure needed to apply ink to paper. The PenAgain’s “Y” formation allows your hand to relax and guide it, rather than forcefully grip it, which reduces hand fatigue, making the PenAgain™ ideal for those who spend much of their days writing as well as those suffering from carpal tunnel syndrome, calluses, repetitive stress injuries, hand tremors and arthritis. Soft rubber coating provides a comfy, tension-free writing experience. Therapy Benefits: Reduces hand fatigue Reduces pain and discomfort when writing Tension-free writing experience Supports people with carpal tunnel syndrome, calluses, repetitive stress injures, hand tremors and arthritis Product Features: Blue outer pen with black ink 2 black refills included Comfortable "No Grip", soft-touch coating design reduces stress on the hands & fingers Pocket clip & retractable cap Approximate size: Length: 103mm, Width: 42mm, Height: 10mm Additional refills are also available separately, or as part of a bundle
