The finest British-made fountain pen ink suitable for all pens. Nature is overflowing with the richest array of greens, and we were spoilt for choice when looking for inspiration for this particular shade. A deep blue-green, like the plumes of a mallard duck, we hope you love this bottle of inky goodness as much as we do.

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!

  • Each bottle holds 50ml of this lovely ink, enough to keep you going for reams of writing, drawing, or doodling.
  • All our inks are water-based, acid-free, non-toxic, and vegan-friendly.
  • Each ink comes beautifully presented in a stunning bottle with an antique laid paper, gold-foiled label.

Our fountain pen ink is compatible with all Tom’s Studio Pens, including calligraphy (The Flourish, Carrot, and Bloom), fountain (The Studio and Studio Pocket), and fineliner (The Lumos and Lumos Mini).


Fountain pen inks are highly 'layerable', allowing you to build different intensities or colours by applying more or less ink on the paper. Please note that the colour on the label may not perfectly represent the colour achieved when using different pens or techniques.


Because the ink has such a concentrated colour, you can dilute it with a smidge of water (ideally distilled) to create watercolour-like washes and depth of colour.

Shipping costs are calculated at checkout.

Lovely pen. Writes like a dream and is just a perfect size when closed. Great product. The engraving in
script is small as others have said, but that’s just fine for me.😊

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.
