Noodler's Baystate Blue (3oz)
3oz (90ml) bottle of Noodler's Baystate Blue fountain pen ink. The Noodler's Baystate inks are slightly different formulas than conventional fountain pen inks. They are designed to be more vibrant than other inks and have a slightly basic pH-level, and as a result they are prone to staining and should not be mixed with other non-Baystate inks. If staining should occur, a solution of 10% household bleach and 90% distilled water will clean it up. If you have any particularly rare or valuable pens, you may want to avoid using Baystate inks in them.
