The finest British-made fountain pen ink suitable for all pens.
Named for the deepest point of the ocean - the Marianas trench - this deep blue ink reflects the ocean’s mystical depths.
Most pens offer ink cartridges in a limited selection of colours, Tom wanted to change that by developing 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 for reams of writing, drawing or doodling.
• All of our inks are water-based, acid-free, non-toxic and vegan-friendly.
