The finest British-made fountain pen ink suitable for fountain and calligraphy pens. The epitome of summer refreshment, this vibrant watermelon pink with dazzling golden shimmer will quench your thirst for vibrant colour. Envision sinking your teeth into a perfectly ripe wedge straight from the garden patch.

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 shimmer fountain pen ink is compatible with Tom’s Studio calligraphy (the Flourish, Carrot, and Bloom) and fountain pens (the Studio and Studio Pocket).

Please note that it is not suitable for use with our fineliner pens (the Lumos and Lumos Mini) or 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.

Watermelon ink

This is a beautiful soft red colour with a vibrant gold shimmer. It glides on to the paper and the wider the pen stroke the more the gold shimmer is visible. I am really enjoying using it.

Beautiful gold. Hard to do it with an ink. Well done

The prettiest ink I own

I bought two of the shimmer inks (Stellar and Amethyst), and they're both fantastic. Amethyst is the loveliest shade of purple with ample amounts of shimmer. I'm sad that I have to use up the ink in my fountain pens before I can fill them with this ink. Truly the loveliest ink I own.

Gorgeous dark ink

I bought two of the shimmer inks (Stellar and Amethyst), and they're both fantastic. Stellar is dark with just the hint of a shimmer; I prefer it to my other black inks. I'm excited to fill my fountain pens with it.
