This is the bottle that has earned Diamine its place on writing desks the world over.

Made in Liverpool and presented in the brand's signature glass bottle, the 80ml fountain pen ink is a water based, dye based formula that lays down rich, dependable colour with the easy flow that everyday writing asks for. It is non toxic, acid free and vegan friendly, and it is well suited to fountain pens of every kind, with a particular reputation for treating vintage pens kindly.

At a generous 80ml, a single bottle will see you through many seasons of letters, notes and pages, which makes it a quietly economical choice as well as a beautiful one. Whether you are filling your first pen or returning to a long loved favourite, this is the ink to write-draw with day after day.
