Super Big Fat Pens have a large diameter barrel, 1 inch (25.4 mm). People with arthritic hands who would otherwise have difficulty grasping and/or pinching find this size easier to hold that other commercially available pens. The wide rounded profile does not force your fingers into some "ideal" ergonomic grip. It will accommodate many alternative ways of being held, the one most comfortable for you! (NOTICE! Amazon shows this pen in its search for "weighted" or "heavy" pens. This pen actually only weights 1 oz. and may not be the best choice for people with tremors; although many customers who have Parkinson's still find them helpful) 

MY STORY: My wife has had arthritis since she was 13. For years she has tried all kinds of pens: foam grips, ergonomic shapes, etc. Some are okay but this pen works best from her. This is a super big fat pen that works for people with arthritis or anyone with limited dexterity. My wife loves this pen. Now you too can enjoy this truly useful and comfortable pen. She found that fancy ergonomic styles, ring pens, and foam grips just do not work that great for people with arthritis. You do not need a fancy pen, just something big, fat, and easy to hold.
