Longbill Spearfish

Longbill Spearfish ink swims the page with the cool, crisp essence of an ocean breeze. This moderately saturated hue renders shades that transition from a refreshing cerulean to the dusky blue of the deep sea. Longbill Spearfish is part of the Keystone Formula fountain pen ink line, our traditional dye-colorant ink. The 60mL volume will provide approximately 75 standard converter refills assuming a 0.8mL draw.  Enjoy Longbill Spearfish as a standalone fountain pen ink, or blend it with other Birmingham Pen Co. fountain pen inks to craft your personalized shade.
