This brush is ideal for a variety of techniques, including calligraphy and watercolor. Sumi brushes are unlike watercolor, oil and most other paintbrushes as the brush is are composed of two separate parts. The central core, which determines the height and basic function of the brush, is made of relatively stiff hairs gathered to form a tapered point, while the outer wrapping consists of softer hairs which are selected for their greater water-holding capacity and for facilitating smooth strokes. This design ensures smooth maneuverability and dynamic strokes, whether light or heavy pressure is applied. It features a combination of horse, badger, deer, and sheep hair of the same length that come to a point when dipped into water.Details:Media brushAvailable in multiple sizesNatural filament blendDurable shaftFor use with a variety of techniques, including calligraphy and watercolor
