Diamine Ink Cartridges

For our Signati fountain pens, we have chosen what we believe to be some of the finest inks in the world — Diamine inks from the United Kingdom, a globally renowned manufacturer with a long-standing tradition.
Diamine inks are known for their wide range of vibrant colors and subtle shades, achieved through varying levels of pigment concentration. This allows each writer to find the perfect hue to match their personality or mood.

We’ve tested many options, and Diamine inks proved to be the ideal match for our pens. They are water-based, which helps prevent the ink from drying out too quickly in the nib — a common issue with fountain pens. Another undeniable advantage is their eco-conscious composition, offering a more sustainable writing experience.

Diamine inks are available in convenient 30 ml bottles or as standard international ink cartridges
