It all began in 1883, in a small shop near the University of Heidelberg, where it was already possible to purchase Kaweco iron-gall ink. Over the years, the ink and writing instruments have evolved, always maintaining quality as a top priority. Kaweco ink is water-soluble, cruelty-free, and 100% vegan. Compatible with any type of fountain pen, Kaweco ink is ideal for use with Kaweco converters, available in three sizes and various colors. The converters function as reusable cartridges, making their use highly sustainable.
