Winsor & Newton - Series 7 Kolinsky Sable - Mini Round - Size 2 - 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. The unique features of a Series 7 Round Miniature brush are its wider belly coupled with a long tapered point while still offering sizes that range into the smallest of round brushes. A round brush shape is good for a range of thin to broad strokes. Its point makes it easy to use in tight areas.
