Saiboku Aya colored ink sticks are like traditional black sumi ink, but with a variety of vibrant colored pigments, not just lamp black. Mixed and shaped by hand by artisans at Boku-Undo in Nara Prefecture, Japan, these beautiful ink sticks are made with the highest quality, finely ground pigment. We stock the entire Saiboku Aya lineup, with eighteen saturated colors for watercolor painting, calligraphy, and Sumi-E.
