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 Bungujoshi
Bungu Joshi Haku (the 'Stationery Girls Expo') is Japan's largest stationery festival, first held in December 2017. Run by an executive committee with support from Segmo and the Nippan Group, it lets visitors browse and buy tens of thousands of stationery items directly from manufacturers, and event-exclusive goods are released under the Bungujoshi name.
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.
