Pigment-rich, waterproof, and lightfast – what’s not to love?

Great news: my amazing pigment-based waterproof ink works perfectly in a fountain pen as well as the Lumos. This means UV rays don’t stand a chance; nothing is being dulled here! You can confidently lay watercolours or other inks on top without fear of bleeding.

Made in the UK, this ink rivals the finest American, Japanese, and German equivalents.

  • 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).

Pigment Black dries a matte charcoal black. It's worth waiting a couple of hours before applying washes over the top of the ink to be sure that it is completely dry.

Be sure to cap your pen when not in use. Please do not store your fountain pen for long periods of time with this ink, as it may clog the feed. We recommend rinsing your tips out weekly.

Even when capped, ink can evaporate from the tip leaving it a little dry. If this happens just dip in a little water and scribble until you see the ink flowing again.

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.

Fountain Pen

Bought as a gift for my daughter, she loves it and says it's the best pen she's ever had.

I like it however…

I recently happened to read a reply to a question on social media regarding your ink, and would it be archival and good for artists to use, and your answer was to get a different brand ink. This is after I’ve confidently used this ink in an artwork. Hm.

Hi Lulu,

Thanks for your message, could I just check which comment you are referring to and which ink? Our new pigment ink is archival, so if we have made a mistake on a post it would be super helpful to know which so we can double check it. Thank you! Gemma
