Check out the entire collection of ink available from German manufacturer Kaweco.
It all began in 1883 in a small shop near Heidelberg University. It was already possible to purchase the Kaweco iron gall ink at this early stage. Over the years, the ink and the writing instruments developed further, but the quality remains the top priority. The Kaweco ink in the color pearl black is water-soluble, cruelty-free and vegan.
