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.

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 Gridberry?
Gridberry falls into Inktend's purples family based on its typical swatch color.
Does Gridberry have sheen?
Gridberry 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 Gridberry?
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 Gridberry?
It behaves predictably on most fountain-pen-friendly paper. Stick to something reasonably absorbent-resistant, since cheap copier paper dulls saturation and can feather.
