PLATINUM Chou Kuro Bottled Fountain Pen Ink


"Chou Kuro" translates to "super black", and this fountain pen ink from Japanese pen maker PLATINUM certainly lives up to its name. After receiving many requests over the years from fountain pen users for a blacker ink, PLATINUM has released this new ink, which they describe as being 46.8% darker than their popular Carbon Black ink. It offers excellent legibility on paper with an intense black colour while also being highly water- and fade-resistant.
