Kaweco Fountain Pen Ink Cartridges - Ruby Red

$5.25
Minus Plus

Ruby Red is one of the vivid shades in Kaweco's ink cartridge lineup, a deep red-toned ink that fills fountain pens with rich, saturated color from the first stroke. It flows smoothly and dries at a reasonable pace, making it a good choice for everyday notes as well as letters that deserve a little more warmth on the page.

Each cartridge is the standard international short size, so it fits most fountain pens that take universal cartridges, not just Kaweco's own. Simply pop one in and write, then swap in a fresh cartridge when the ink runs low. The box reads "Germany, since 1883," a nod to the brand's long run making writing instruments.
