The No-Grip Ring-Pen by Grandee - Detailed Information Sheet

The first true innovation in writing tools in thousands of years - a pen which
provides stability and control without gripping!
The original ergonomic pen and still the best!
The RingPen is the direct result of prolonged research which began in an aerodynamic laboratory 20 years ago and is based upon concepts normally applied in the study of aerodynamics and the theory of stability. The development of the RingPen represents the first time in history that the precepts of math and science have been applied to the design of a writing instrument. The final result is a truly ergonomically designed pen that is fluid in writing and fatigue free.
Don't accept cheap halfway imitations which don't provide the proven benefits of the Ring Pen
