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 Pure Pens
Pure Pens is a family-run fountain pen specialist retailer based in South Wales, United Kingdom, trading since 2004. Alongside major pen and ink brands, it sells its own Pure Pens line of bottled fountain pen inks. The company operates as one of the UK's established online destinations for pens, inks, paper and accessories.
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.
