Graf von Faber-Castell Cartridges Violet Blue
The manufacture of Graf von Faber-Castell's indelible inks for fountain pens is an art form. Each one of their 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 waterproof, cannot be erased and is resistant to many chemicals and solvents.
