Paper & pairing
Purples sit at the boundary of professional and playful, one of the more personality-forward choices that still reads clearly on the page. 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 Octopus Fluids
Octopus Fluids is a family-run ink manufacturer in Dresden, Germany, producing writing inks, calligraphy inks and specialty fluids in its own facility. Alongside classic bottled fountain pen inks, its flagship Write and Draw line comprises 38 pigmented, water- and smudge-resistant inks with playful colour-plus-animal names, many meeting document-proof standards.
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.
