Diamine has manufactured in England since 1864. Diamine ink is safe to use in all brands of fountain pen and is one of the finest inks available. The huge range of over 100 colours are all water-based, acid-free and non-toxic, and are vegan-friendly.
The WES Imperial Blue was a special edition for the 25th Anniversary of the Writing Equipment Society, which was popular enough that the colour has become a permanent fixture on the Diamine catalogue. Monaco Red was formulated for Prince Rainier III of Monaco and the Grimaldi family.
