Tom's Studio Fountain Pen Bottled Ink Pigment Black

$20.18

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.

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.


  • Made in the UK
