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 Bungubox
Bungubox is a Japanese stationery shop founded in 2012 in Hamamatsu by Kaoru Yamagishi, and it later opened a Tokyo presence. Under the motto "Ink tells more," the shop specializes in fountain pens and its own line of original inks, which are manufactured for the store by Sailor. Its evocatively named house colors have become cult favorites among ink collectors worldwide.
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.
