The finest British-made fountain pen ink suitable for all pens. While it won’t taste as good as blackcurrant liqueur (and we certainly wouldn't recommend having a sip), hopefully this beautiful shade of deep red looks just as delicious as the real thing.

Transform the way you create with an ink colour that sets you apart!

Most pens offer ink cartridges in a limited selection of colours. I want to change that by bringing you this range of beautifully rich and distinctive inks – with no need to dispose of or replace an empty cartridge.

These wonderfully free-flowing inks come in a number of beautiful and nuanced shades. They truly are a joy to write or create with!

Smooth and Beautiful Ink

This purple ink is gorgeous and royal!
To Tom’s Studio I’m increasingly loyal.

I have searched for the perfect purple, and this #11 is it. It’s my fourth bottle of Tom’s Studio (I also have #1, #76, and #78), and I can’t imagine using any other ink.

Beautiful Ink Color

This Tom’s Studio blue ink, Marianas, is breathtakingly beautiful. This probably sounds silly but it calms my soul as I’m writing with it. Need I say more?
