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 Kiwi Inks
Kiwi Inks is a small American maker of handcrafted fountain pen inks, run by a two-person team. Every bottle is mixed by hand and finished with a hand-painted label showing the ink inside, and the shop offers customization such as adjusting wetness, shimmer or sheen to suit a specific pen, with the lineup rotating every one to two months.
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.
