Sumi no Sei Suibokuga No.31 Blue Ink 100g (Boku-Undo)

This concentrated ink, made with pure plant-derived pine soot, is specifically formulated for ink painting, achieving a balanced blend of absorbent black when thick and clear, bright blue tones when diluted.
Blue particles are several dozen times larger than brown particles, so using the undiluted solution may not work for framing. If framing is desired, be sure to dilute the product at least three times.
This product uses a synthetic adhesive. Please note that products made with animal glue and synthetic adhesives cannot be mixed.
