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.

*Waterproof? Well, almost. Our ink is highly water-resistant, meaning it’ll stay true under a colour wash – provided you’ve given it time to fully dry. But if you go in heavy with a very wet overwash, you might notice some smudging. Unlike true waterproof inks (which often contain plastic binders), we’ve formulated this one to work beautifully with the Lumos – balancing flow, performance, and durability.

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

Black as night & watertight

What’s not to like? This is exactly the ink I needed for my Lumo pen. Now I can splash watercolour washes over my line work without fear of the line dissolving into a grey mess. Thankyou for a perfect product.
