Diamine have been producing world-renown inks in England since 1864, the first choice of ink for many pen connoisseurs and collectors.
To celebrate their 150th Anniversary, in 2014, they launched a collection of sixteen fountain pen inks. Each ink is presented in a triangular wedge-shaped bottle, forming a circle when all sixteen inks are collected.
Each glass bottle contains 40ml of ink in a shade unique to the 150th Anniversary collection. Made in Liverpool, England.
