Graf von Faber-Castell Cobalt Blue is a document ink, water-resistant, uv-resistant and resistant to certain chemicals. This ink is beautiful to write with and makes the perfect every day ink. With 6 beautifully presented cartridges it is a must have for any desk.

The manufacture of Graf von Faber-Castell indelible inks is an art form. Each one of the 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.
