Conceptualized and created by Pilot Pen, Iroshizuku ink is a cult favorite. 

The name "Iroshizuku" is a combination of the Japanese words "Iro," which means "coloring" and expresses high standards and a variation of colors, and "Shizuku," which means "droplet" and embodies the image of dripping water. 

Each individual ink name derives from expressions of beautiful Japanese natural landscapes and plants, and inspires depth within each unique hue.
