With origins dating back to the 1800s, Diamine Ink boasts a rich history and has evolved into one of the finest quality fountain pen inks available today. Its reliability has made it a favourite among both professionals and beginners alike.

Diamine Prussian Blue  Ink is compatible with all brands of fountain pens, offering a versatile and convenient option for any writer. This water-based, non-toxic ink is safe to use, even with vintage pens. Its versatility extends further, as it can be easily mixed with other colours to create custom shades.

The Prussian blue colour of this ink is not overly saturated and thus has a beautiful depth to it. A blue-grey or blue-black ink from the standard range, Diamine Prussian Blue is a nicely saturated colour with a vintage look to it. It's darker, less green leaning and more saturated than Indigo, and it flows better and feels more lubricated when writing across the page.

 Additionally, Diamine Ink's anti-clogging formula ensures smooth, consistent writing performance. Golden Brown variant is a medium warm brown with medium shading, drying in 40 seconds on Rhodia paper with a medium nib, and providing an average flow.
