The production of our indelible inks for fountain pens is an art in itself.
Each shade is inspired by nature and requires its own formulation and top-quality components, as demonstrated by the regularity of the ink flow and the fact that you can write almost immediately, even after long pauses.
An ink is indelible when it does not smudge, when it is reproducible, unalterable by light, when it cannot be erased, and when it is resistant to washing, water, and most chemicals and solvents.
