After trying countless ink brands Diamine has to be my favourite, with beautiful fade and un-parrelled flow, it's a joy to write with. Diamine ink has been manufactured in England since 1864 and is safe to use in all brands of fountain pen and works especially well with the Studio Pen Flex Nib. All are water-based, acid-free and non-toxic, and are vegan-friendly.
These inks really do live up to their reputation as some of the finest available.
The Diamine bottle is also a great addition to your desk with it's wonderful retro design!
Bottle contains 80ml Earl Grey Ink (approx 2.8 fluid oz).
