Diamine 80ml bottle of high quality 'Amazing Amethyst' coloured ink, also available in 30ml bottles.
If you have a fountain pen that is designed to be filled from a bottle of ink, or have a fountain pen converter fitted then you have a door into the world of fountain pen ink. There is almost every colour imaginable available, from all sorts of different brands. Part of the fun of fountain pen ownership is exploring all of these different colours, and brands to find your favourite, some people have multiple colours on the go at once, in different pens.
It’s not just fountain pens that can be filled with ink from a bottle, some high end technical drawing pens can too, and you’ll find all of these here, along with unique speciality inks like registrars ink.
