Paper & pairing
Greens read as more expressive than blue or black, a common choice for people who want color without leaving the realm of "still looks professional." 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 Kawasaki Bunguten
Kawasaki Bunguten is a stationery shop in Ogaki, Gifu Prefecture, Japan, founded in 1923. Its owner is renowned in the Japanese fountain pen community as an ink blender who has created more than 1,000 original inks over the years, with several hundred colors, many themed on local Ogaki culture and literature, available in the shop's dedicated ink corner.
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.
