Paper & pairing
Warm tones (oranges, yellows, ambers) show strong contrast between light and dark areas of each stroke, which is part of why they're popular with broader nibs. 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 Bungukan Kobayashi
Bungukan Kobayashi (also known as Stationer's Kobayashi) is a stationery retail chain based in Shizuoka Prefecture, Japan. The shop is known for its store-exclusive fountain pen inks manufactured by Sailor, including a large Shizuoka-inspired series drawing on local landmarks such as Suruga Bay, and it has also collaborated with Tono & Lims.
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.
