Toms Studio Fountain Pen ink 01 Deep Black 50ml

The finest British-made fountain pen ink suitable for all pens. Classical doesn’t have to mean boring. Deep, dark, and long-lasting, this tried-and-tested favourite isn’t simply ‘black’ – it’s every colour combined to create the deepest of blacks.

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 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).

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.
