Where 16th Century Ink Meets 21st Century Artistry
The Saibiboku 20-Color Set is the result of a rare collaboration between Kissho of Kyoto, renowned pigment makers, and Kobaien of Nara, sumi ink masters since 1577. Each pan is handcrafted with Five Star Kouboku sumi ink, natural binders, and ultra-fine pigments to create a watercolor palette unlike any other, smoky, layered, and quietly luminous.
Rather than bold primaries, the tones here are muted, fluid, and meditative, ideal for sumi-e, Nihonga, calligraphy backgrounds, botanical studies, and atmospheric illustration. This set captures the ancient soul of ink while offering the versatility of modern Gansai watercolors.
