KWZ born in 2021 from the Dr. Konrad Żurawski, a graduate of the Faculty of Chemistry at the Warsaw University of Technology. At the beginning Konrad wanted to improve the saturation of one of his fountain pen ink, discovering a spectacular world.
The collection of KWZ inks are made of two groups: standard fountain pen inks and iron gall fountain pen inks. Every product have flow characteristics optimized for use in fountain pens.
Iron gall fountain pen inks become darker with the time and penetrate deep into the structure of paper which made the text written with them remarkably stable and waterproof. Due to the chemical composition of iron gall ink we suggest to use this kind of inks only on a fountain pen that you use every day. Don't leave the iron gall inks unused inside your fountain pens.
KWZ IG Gummiberry is an iron gall fountain pen ink and comes in a glass bottle of 60 ml. The amber glass of its bottle protects the ink fro the UV light.
