Paper & pairing

Greens read as more expressive than blue or black, a common choice for people who want color without leaving the realm of "still looks professional." 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 Ostrich

Ostrich (Tuoniao) is one of China's oldest ink manufacturers, established in Tianjin in 1935 and later operating as Tianjin Ostrich Ink Co., Ltd. The company developed its blue-black iron gall ink in 1942 and today produces fountain pen, calligraphy and other inks, exporting to some twenty countries and regions across Europe, America and Asia.

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