Private Reserve Ink has created the Infinity Fountain Pen Ink with E.C.O. (extended cap off) Formula.

This ink technology is truly a game changer for the fountain pen industry. When using this ink, you can leave the fountain pen capless for longer periods of time. The ink has been tested in a pen with its cap off for many hours and the performance was stellar. If you write with a fountain pen intermittently, theoretically, it can be cap-off for ‘infinity’.

Size: 60 ml
