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 Anderillium
Anderillium is a small family-run American ink maker producing small-batch fountain pen inks inspired by the natural world. Each color is named for a real animal and grouped into themed series such as the Avian, Cephalopod, Lepidopteran, and Ichthyoformes collections, sold in distinctive 1.5 oz bottles. The inks are formulated in-house and have become favorites among nature-loving pen users for their evocative, well-researched palette.
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.
