The Escoda Series 5131 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 12 round brush with bristles measuring a diameter of 6. 9mm and length of 30mm.
