The Escoda Series 4628 Clasico Brushes are made from only the finest white hog bristle found in the Chungking region of China. The natural hardness of the bristle responds perfectly to more or less dense oil and acrylic painting techniques. Escoda brushes continue to be made by hand by the Escoda family as they were since 1933. This is a long handle size 18 bright brush with bristles measuring a diameter of 17.1mm and length of 23mm.
