The production of waterproof pen inks is a form of art. Each of the various vibrant colors, inspired by nature, requires its own formula and the highest quality materials. The exceptional quality is demonstrated by the consistent ink flow and the fact that you can start writing with the pen almost immediately, even after long pauses. An ink is called waterproof if it is resistant to smudging, reproducible, lightfast and permanent, cannot be erased, and is resistant to many chemicals and solvents. The elegant glass bottle of ink becomes a valuable decorative item for any desk. All Graf von Faber-Castell inks are also available in ink cartridges.
