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