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.
