Keroushi Green
Usagiya is one of the 713 brands in Inktend's built-in ink catalog.
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 Usagiya
Usagiya is a stationery specialty shop based in Okayama, Japan, with stores in Okayama, Kurashiki and Fukuyama. In collaboration with Sailor it produces an extensive line of original fountain pen inks, with dozens of colors inspired by regional landmarks and products such as Bizen pottery, Kojima denim and the Setouchi coast, and Sailor also operates an ink-blending workshop at its Okayama store.
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.
