Rembrandt watercolor brush series 110 made of natural Kolinsky red sable hair. Traditionally, brushes have been made from natural animal hair, and Kolinsky red sable is the most prized for its water and pigment retention, and its flexibility. Rembrandt watercolor brushes are manufactured with the utmost care and traditional craftsmanship; each bundle of hair is hand-shaped and set in a nickel-plated brass ferrule.
