Winsor and Newton Series 7 Kolinsky Sable Brushes - at least 40% off - Winsor and Newton Series 7 is the world's finest water colour brush. 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 water colour brushes in her favourite size; the No.7. Today, Series 7 is manufactured from only the finest pure Kolinsky Sable hair, in rust-proof, seamless nickel plated ferrules with black polished handles. Winsor and Newton Series 7 uses only the highest quality raw materials and enjoys hand made manufacture by our brush makers with years of experience. For larger sizes, each brush is packed into an individual box with a tag included to indicate the name of the Series 7 brush maker who made that particular brush.
