Noodler's Baystate Blue ink in a 4.5 oz bottle. Baystate Blue is a forgery-resistant, waterproof, and vibrant blue ink. Bottle includes a free fountain pen!
Noodler's Ink bottles come filled to the brim, so be careful when opening!
The vibrant colors from Noodler's Baystate lineup comes with a caveat: Its unique pH levels can stain parts of your pen and/or anything it comes in contact with (porous surfaces like sinks). Feed sections, converters, demonstrator pens, and plastic pen parts are susceptible to permanent staining. We do not recommend using Baystate ink in any demonstrator or expensive pen unless you plan on dedicating that pen to this ink or accept the risk of stained sections.
