Winsor & Newton is the finest kolinsky sable brush available. Hand made using the finest materials. World class. Series 7 Kolinsky Sable Miniatures Brushes are the same superior quality as standard Series 7, and contain the finest pure Kolinsky Sable hair. The only difference is that the hair is comparatively short out of the ferrule, so that the point of the brush can be more accurately controlled during the most delicate work. Rust-proof seamless nickel plated ferrules and black polished handles.
I personally use this brush for my daily painting. I highly recommend them.~Tim
