Manuscript Pen-Squirrel Hair Calligraphy Brush. The supple and resilient combination of the hairs make this set ideal for Sumi-e painting, Chinese calligraphy scripts, ink wash painting and tinting. The core of the brush tips are short for strength and ink retention, surrounded by an outer layer of long hairs that make up the supple tip. Assembled to a bamboo handle. For use with Chinese inks & water based paints only. This package contains one large squirrel hair calligraphy brush. Imported.
