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 Ultra Green 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.

Diamine's Ultra Green, despite the name, isn't a very bright neon green, but instead a very saturated, deep, and rich shade of spring green with hints of blue.

 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.
