Chou Kuro is Platinum’s flagship black ink, engineered to deliver an exceptionally deep, rich black that gives your writing maximum contrast. On paper it dries to a flat, matte-style black with no unwanted shine or colour undertones — a pure, clean black ideal for bold statements, archival writing, or professional documents.
The ink flows smoothly and generously from the pen, so even broad or wet nibs put down consistent, saturated black strokes. On fountain-pen-friendly paper it shows no shading, no sheen, and no glitter — just a dense, uniform black tone that reads clearly and sharply. Because it’s pigment-based and water-resistant, Chou Kuro is well-suited for notes, letters, journals, or any writing where permanence and readability matter.
