Viceroy Butterfly Orange
Small-batch natural-history inks organized into Avian, Cephalopod, Lepidopteran, and Ichthyoformes series, each color named for a real creature.
Specs
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 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.
