Sumi is the colour of traditional Japanese black ink used in calligraphy.
Shachihata 'Iromoyo' ink pads are influenced by traditional Japanese colours used in arts, textiles, and crafts. The ink is such that it is easy to produce a clear image even with stamps that have intricate designs and it does not bleed through most papers. Ink is acid-free, oil-based, and waterproof (when completely dry). There are 24 colours to choose from making it easy to select colours to suit your style and theme.
