The PenAgain Ergosof is seen by many as "the world's most comfortable pen". It's certainly a fine pen. Especially for anyone who suffers writer's cramp, has writing difficulties, a touch of arthritis, or is just sick of pens going AWOL from their desk.
The patented PenAgain wishbone shape begs you to thread your index finger between the two arms. This causes the hand to relax, and leaves the weight of the hand to hold the pen in place. Stress on the hand, wrist, and forearm disappears.
The PenAgain Ergosof has a comfortable soft rubber coating, a pocket clip, retractable cap, and comes with two refills. And it looks just strange enough that the whole office would know it's your pen and not to 'borrow' it.
