The Jack Richeson Sumi Ink Brush is a traditional-style sumi brush, ideal for ink, calligraphy, sumi-e, and watercolour. Its fine responsive tip gives you control, elegant line work, and more expressive movement, making it especially useful for lettering, linear drawing, and detail. Made with horse hair, it is a brush for artists who want clean marks with natural flow. A beautiful choice for work that needs both precision and character.
