Diamine

 

The history of fountain pen ink manufacturer Diamine dates back to 1864 when the company was founded by T Webster and Co. in London. The business moved to Liverpool in 1925 and T Webster and Co. changed its name to Diamine in 1964. 

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.
