This hair comes from the Siberian and Manchurian Sable, better known under the name of Kolinsky. It is a small animal that lives in the coldest areas of these regions, giving it a very strong and dense hair, an ideal hair for watercolor. It has fantastic spring, snap, and color-holding ability.
The Raphaël Kolinsky Designer Quill Brush features a long, tapered point and smaller belly for rapid and precise work. The quill ferrule is traditionally crafted without ties, which makes the brush extremely lightweight and easy to handle.
