Diamine has been manufacturing ink in England since 1864. Over that time the product range has changed hugely, but the quality has always stayed high.
With 2014 being the company's 150th anniversary, Diamine created a new range of inks. Supplied in special triangular bottles, this is an ink collection that is meant to be collected!
Triangular bottles each contain 40ml of ink and 8 of them can be arranged into (rather fittingly for an anniversary) a 'birthday cake' shape!
Diamine ink is safe to use in all brands of fountain pen and is one of the finest inks available. It's also vegan-friendly.
