DIAMINE Fountain Pen Ink

Diamine have been making ink since 1864 and are one of the last remaining manufacturers in the UK. Their superb fountain pen ink in a smaller 30ml bottle is perfect for trying out a range of colours, or if you just don't use ink quickly enough to need a larger bottle.

Diamine ink is safe to use in all brands of fountain pen and is one of the finest inks available. By adding a secret ingredient to de-stress the surface, Diamine achieves vibrant colour with free flow that glides along the paper and doesn't clog your pen. The range are all water-based, acid-free and non-toxic, and vegan-friendly.

The handy 30ml plastic bottle is easier to carry, and the tall slim design means you can use more of the ink without having to tip the bottle at awkward angles. We would advise filling your converter directly from the bottle, when using a larger fountain pen. 

Fun fact: Monaco Red was formulated for Prince Rainier III of Monaco and the Grimaldi family. Diamine Royal Blue was used by presidents Obama and Medvedev to sign the nuclear arms treaty in April 2010.
