Platinums Classic Inks range is the definition of under-the-radar. Water resistant and very well behaved, these are some really beautiful and appropriately classic colours from one of the Big Three Japanese penmakers.

Developed in collaboration with a Japanese fountain pen enthusiast known only as Gary these inks are modern Iron Gall inks. For those unfamiliar, Iron Gall inks have been made for centuries and are highly water resistant as the ferrous sulphate content of the ink causes it to bond permanently to the paper.

Platinum Classic #15 Cassis Black is a rich burgundy almost oxblood red that, over time, will darken as the iron sulphate bonds with the page.

Each Platinum Classic ink comes in a 60ml glass bottle.
