Color: Negro Carbón Cartuchos de tinta estándar - negro carbón 6 ink cartridges, Carbon Black The manufacture of our indelible inks for fountain pens is an art form. Each one of our different vibrant colours inspired by nature requires its own formula and the highest quality ingredients. The excellent quality shows itself in the even flow of ink and the fact that you can start writing with the fountain pen almost immediately, even after long breaks. An ink is called indelible if it is smudge-resistant, reproducible, light-fast and permanent, cannot be erased and is resistant to many chemicals and solvents. The elegant glass bottle of the ink becomes a precious ornament for every desk. All Graf von Faber-Castell inks are also available as ink cartridges.
