KWZ iron gall inks

KWZ iron gall inks are particularly durable and waterproof inks that are ideal for everyday use. They are characterized by their unique color development on the paper, where they develop an intense, dark color. These inks have been developed and optimized by KWZ in Poland to ensure high stability while minimizing the possibility of corrosion in well-maintained fountain pens. Nevertheless, it is important to write regularly and to clean the fountain pen thoroughly during longer breaks to ensure optimal results and a long lifespan of the writing instrument.
