The Finest British Made Fountain Pen Ink Suitable for All Pens Much requested and finally here – our Sepia ink is a warm, vintage brown that feels like it’s been lifted straight from an old love letter. Perfect for notes, sketches, and anything that deserves a touch of old-school charm. 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!
