Diamine x Niche Pens Alexandrite Fountain Pen Ink

2019 marked our 15^th anniversary of selling pens, inks and stationery accessories on our two websites. We wanted to mark what’s a special time for us with something that will be really, really special for you!

We've named the ink 'Alexandrite' - a 15th anniversary gemstone, with unique colour-changing properties depending on the time of day. A deep teal in daytime light, to a rich red when the light starts to fade at dusk. Our ink, too, changes colour and sheens with changing light perspectives.

Available in 30ml plastic bottle or 80ml glass bottle.
