PLATINUM Classic Ink 60ml Forest Black

An unusual range of inks made by a traditional Japanese method which only Platinum still use. The dark colours will change over time after the ink dries. The dry ink on the page will oxidise with exposure to the air, darkening, and becoming closer to black as time passes. The same process also makes the ink more permanent on the page - it's the same type of ink used by registrars for documents that need to stay readable for centuries - often known in the west as 'iron gall' ink. There are a handful of blue-black inks of this type available these days, but it's very rare to find a range of colours.
