Diamine has been making ink in Liverpool since 1925, and Forever Ink is the range built around a single idea: marks that last.

This is a pigment based formula rather than a conventional dye, so the colour is designed to stay waterproof once dry and to resist fading in daylight, holding true long after a page has been closed and opened again.

It flows through fountain pens and lends itself just as readily to brushes, dip pens and calligraphy, which makes it a natural companion for anyone who likes to write-draw across more than one tool. Because the colour sits in pigment rather than dye, you can layer Forever Ink over your favourite dye based inks without one bleeding into the other, which opens up washes, underlines and mixed media work with a confidence ordinary inks do not allow.

Each bottle holds a generous 50ml, enough to carry you through a great many pages of considered, lasting work.

NB: Pigment inks reward regular maintenance. We recommend flushing your pen periodically and not leaving Forever Ink sitting unused in a pen for long stretches, so the feed stays clear and the flow stays smooth.
