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.

  • Each bottle holds 5 ml of this lovely ink.
  • All our inks are water-based, acid-free, non-toxic, and vegan-friendly.
  • Each ink comes beautifully presented in a dinky glass bottle with a handy pipette for easy application.
  • Every mini ink is bottled by hand by the Tom's Studio team and packaged in a hand-painted cardboard sleeve.

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), fineliner (The Lumos and Lumos Mini) and the Wren.

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.

We aim to process your order within 1-3 working days. Please note that this increases to 1-4 working days for orders that include any personalisation, such as engraving.

Cute little ink!

I appreciate the mini sizes because I love having options! The ink is very high quality, and Marianas is a perfectly classic blue.

Great Ink and great colour too

I bought this little bottle because I like the more unusual colours of ink but thought I’d best have a “standard” blue too. It’s a wonderful deep blue, great consistency and it flows from the pen nib beautifully too. I’ve been testing it in my Lumos pen but can’t see why it wouldn’t work as easily in a standard fountain pen, I just need to buy a bigger bottle now!
