Airline

Airline is part of the Delicate Formula fountain pen ink line, best for delicate vintage pens* and easily washable from most surfaces with soap and water. The 100mL volume will provide approximately 125 standard converter refills assuming a 0.8mL draw.  Enjoy Airline as a standalone fountain pen ink, or blend it with other Birmingham Pen Co. fountain pen inks to craft your personalized shade. *Please ensure the integrity of any vintage pen ink system prior to usage. Our Delicate Formula is built with gentle & washable colorants, yet we cannot assume responsibility for any damage that may occur in a compromised fountain pen.
