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 prized for its water and pigment retention and its flexibility. Rembrandt watercolor brushes are crafted with the utmost care and traditional artistry; each hair bundle is shaped by hand and set into a nickel-plated brass ferrule.
