Each one of our vibrant ink colors require its own formula and the highest quality ingredients. The fountain ink collection is comprised of colors inspired by nature. The document proof (indelible) colors are smudge-resistant, lightfast, waterproof, cannot be reproduced or erased and are resistant to many chemicals and solvents.
It is recommended to use Graf von Faber-Castell Fountain Inks exclusively with our pens for best performance. If used with unsuitable ink, the instrument may be adversely affected causing damage to the feed. In these cases, part or repair charges may apply.
Always use fresh ink. We recommend a cleaning every three months, any time an ink color is changed, or when the instrument is not in use for an extended period of time.
