The name "iroshizuku" is a combination of the Japanese words "iro" (colouring) expressing high standards and variation of colours, and "shizuku" (droplet), which embodies the very image of dripping water. Each ink name derives from the expressions of beautiful Japanese natural landscapes and plants, all of which contribute to the depth of each individual hue.
