We’ve abandoned the cylindrical shape of a traditional pen. Instead, the Ko-Axis™ Rail Pen leverages the benefits of a flat, wide, rectangular geometry for unparalleled writing comfort and low-profile carry. Rather than cramping your fingers around a thin cylindrical shaft, you can embrace your writing instrument in a more natural way that provides long term comfort with less tension on your fingers. The 4-1/2″ length is optimized to deliver a fluid writing experience in your hand, yet be incredibly compact for convenient everyday carry. The magnetic twin-rail mechanism used to extend and retract the ink refill eliminates the need for a separate cap, ensuring you have nothing to lose. Combined with an instant, no-tool refill replacement method, the Ko-Axis™ Rail Pen will always be your pen of choice. Its elegance, comfort, and simplicity will make you wonder why this never happened sooner.
