Diamine have been making ink since 1864 and are one of the last remaining manufacturers in the UK. In 1925 the company created a state-of-the-art production facility in Liverpool, and despite several changes of ownership, they have remained in the same area ever since. Throughout, the Diamine trade mark and the traditional production methods have survived and now in the 21st century their fountain pen ink remains the first choice of many pen connoisseurs.
Diamine ink is a water-based ink perfect for any brand of fountain pen. It is completely non-toxic and offers probably the widest range of quality fountain pen ink colours in the world - in both traditional and contemporary shades.
By adding a secret ingredient to de-stress the surface, Diamine achieves vibrant colour with free flow that glides on the paper surface, and which will not clog your pen.
