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 Tono & Lims

Tono & Lims is a Japanese ink brand founded by fountain pen enthusiast Takashi Ono in partnership with Lim's Lab, an ink producer based in South Korea. It is known for a huge, fast-moving catalog of small-batch inks organized into story-driven series such as Friendship, Legend, Baby Color, Earth Contact and Shaved Ice, plus countless retailer and pen-show collaborations. The playful naming and constant limited releases have made it a cult favorite in the fountain pen community.

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.

Frequently asked questions

What color family is Regulus?
Regulus falls into Inktend's blues & navies family based on its typical swatch color.
Does Regulus have sheen?
Regulus is not typically noted for sheen. If you want that effect, browse similarly colored inks tagged with sheen in the ink library.
How should I store a bottle of Regulus?
Years, easily, as long as it stays capped and out of direct sunlight. The thing that actually shortens an ink's usable life is sitting unused inside a pen, not sitting on a shelf.
What paper works best with Regulus?
It behaves predictably on most fountain-pen-friendly paper. Stick to something reasonably absorbent-resistant, since cheap copier paper dulls saturation and can feather.
