The Winsor & Newton Series 7 is one of the world's finest watercolor brushes. The standards of quality for this brush were set in 1866, when Her Majesty Queen Victoria gave orders that Winsor & Newton should produce the very finest watercolor brushes in her favorite size, the #7. Today, Series 7 is manufactured from only the finest pure Kolinsky sable hair with rustproof, seamless, nickel plated ferrules and polishe, black handles. Series 7 uses only the highest quality raw materials and enjoys handmade manufacture by skilled brush makers with years of experience. Today, just as in 1866, the Series 7 is made for those who understand that the quality of the brush will be reflected in the quality of the work.
