kiwa-guro (pigmented)

Sailor Kiwa-guro is a pigmented black ink renowned for its high water resistance, deep black color, and shiny finish without shading or sheen. It's favored by artists and sketchers for reliable performance on various papers, including copy paper, though its long dry time requires caution to avoid smearing. Ideal for users seeking a permanent, waterproof black that flows smoothly in fountain pens.
