The finest British-made fountain pen ink – now in a mini 5ml sample bottle!

Goddess of the night, Nyx is known to dwell in her mansion at the very boundary of the cosmos. Named for her and her cosmic home, this beautifully purple-toned ink is a clear night sky in liquid form.

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.

  • Each bottle holds 5 ml of this lovely ink.
  • All our inks are water-based, acid-free, non-toxic, and vegan-friendly.
  • Each ink comes beautifully presented in a dinky glass bottle with a handy pipette for easy application.
  • Every mini ink is bottled by hand by the Tom's Studio team and packaged in a hand-painted cardboard sleeve.

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), fineliner (The Lumos and Lumos Mini) and 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.

Shipping costs are calculated at checkout.
