Specs
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 Endless
Endless Stationery is a young Indian brand from the founders' family paper business, first known for its Recorder notebooks with Tomoe River paper. Its Alchemy fountain pen ink line, made in India, offers saturated, well-lubricated colours with mythic and celestial names, including Stardust shimmer editions, in 45 ml bottles.
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.
