About Pelikan
Founded in Hannover in 1838, Pelikan is one of the oldest writing brands still operating, known for its striped Souverän pens and the differential-pressure piston filler it patented in 1929.
Paper & pairing notes
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.
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.
