Paper & pairing

As a near-neutral tone, it reads as professional and safe for anything from journaling to signatures. This ink will behave predictably on most fountain-pen-friendly paper. Cheap, highly absorbent paper (standard copier paper) will dull any ink's saturation and can cause feathering or bleed-through with wetter nibs.

About Birmingham Pen Co.

Birmingham Pen Co. is a two-person American ink and pen manufacturer from the Pittsburgh, Pennsylvania area, originally based in a warehouse on the Monongahela River in Pittsburgh's Southside and now located in Cranberry Township. The name honors the Southside's old nickname 'Little Birmingham', a nod to Birmingham, UK, the historic center of pen and nib manufacturing. The company hand-produces small batches of fountain pen ink in distinct in-house formulas such as Keystone and Everlasting.

Storing and using the bottle

Bottled fountain pen ink has an effectively long shelf life when kept capped and out of direct sunlight: most inks remain usable for years. The main risk isn't the ink spoiling, it's a pen sitting inked and unused for weeks: that's what causes clogs, not the ink's age.
