For when Carbon Black isn’t quite enough, Platinum has come out with their “blackest-black” ink in their 104 year history. Chou Kuro is 46.8% darker than Carbon black. Through the use of pigment, Chou Kuro is water and fade resistant. This long-lasting ink is perfect for documents and journals where permanence is crucial.
Platinum recommends cleaning this ink with distilled water only as the ink can react and stain with the minerals in regular tap water.
