What makes our cartridge special?

The quality of our product is important to us. That’s why we were particularly pleased about the award as a test winner of Stiftung Warentest in the category of ink cartridges in the pollutant test (issue 08/2022).

Is the ink erasable?

Our royal blue ink can be easily erased with the ink killer. We value quality and safety, which is why our highly pigmented ink has been produced in Austria for many years under tested production.
