Japanese brand Sakura started as a crayon company in 1921, and by 1924 had invented Cray-Pas, the first oil pastel that combines oil and pigment. It went on to develop Pigma ink which is used in their Micron and other pens. The ink contains pigment particles of submicron size, resulting in steady flow even through very fine nibs. Pigma pens have become a popular choice among artists, scientists, crafters, and more. In 1984, Sakura invented the first gel-based ink, and continues to innovate and create pens that give us the "Power to Express".
