Private Reserve Infinity Blue – 30ml Bottled Ink

Description:

30ml glass bottle of Private Reserve Infinity Blue fountain pen ink.

The Private Reserve Infinity Ink collection uses the E.C.O. (Extended Cap Off) technology, a new advanced ink formula which allows a fountain pen user to leave their pen uncapped for a longer period of time without drying out.

Your exact results will vary based on your specific pen, environment, etc, but our testing was pretty consistent to be able to leave a fountain pen uncapped for an hour and to have it start writing back up without issue.
