Csontváry-kék
Handmade Hungarian inks steeped in Magyar culture and folklore, from a true family workshop.
Paper & pairing
Blues and navies are the most broadly "safe" fountain pen colors — legible, professional, and unlikely to raise eyebrows in an office. 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 Pennonia
Pennonia is a family-run ink maker founded in 2018 by Máté Bikfalvi, a former teacher, with ink production launching in early 2020. The inks are handmade entirely in-house and inspired by Hungarian culture, folklore, painters and places, while the family operation spans Hungary and the Hungarian-speaking region of Romania where his parents handle bottling and packaging. Pennonia also pioneered mixable liquid mica shimmer additives for fountain pen inks.
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.
