Paper & pairing
Warm tones (oranges, yellows, ambers) show strong contrast between light and dark areas of each stroke, which is part of why they're popular with broader nibs. 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.
