The Finest British Made Fountain Pen Ink Suitable for All Pens   Nature is overflowing with the richest array of greens, and we were spoilt for choice when looking for inspiration for this particular shade. A deep blue-green, like the plumes of a mallard duck, we hope you love this bottle of inky goodness as much as we do. 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. These wonderfully free-flowing inks come in a number of beautiful and nuanced shades.
