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 Sailor Ink Studio
Sailor Ink Studio launched in 2018 as a collection of 100 blended dye inks created by Sailor's ink craftsmen, each identified only by a three-digit number. The line specializes in nuanced, mixed-hue colors that shade dramatically and can shift between hues depending on pen, paper and ink saturation.
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.
