Description Private Reserve Infinity Red fountain pen ink is a rich shade of red that comes packaged in a 60ml glass bottle with a wide mouth and a ridged cap for easier opening and closing. Private Reserve Infinity ink is specially formulated with E.C.O. (Extended Cap Off Time formula) to not dry out in your pen, even uncapped for long periods of time. Under new ownership in 2021, Private Reserve Ink features bright, vibrant colors with excellent flow that tends to be quite wet. Having trouble deciding between colors?
