Takes most of the “shake” and muscle pain out of handling a pen. One finger through the ring creates a solid grip and the ergonomically designed barrel provides a natural resting place for the writing finger. Barrel fits snuggly between two other fingers. No pressure, no pain. Can also be used as a toe pen. Blue ink. Includes two refills. Additional refills can be purchased separately. U.S. Patent #5,391,010 |
