The Da Vinci pipe overgrainer features natural hog bristle hair with high absorbency and is most used for creating evenly spaced lines or abstractions. This specialty brush is good for fluent drawing and abstract area work with brilliant, liquid colors. It features a short plain wood handle and rust-proof steel ferrule, and is made according to certified green manufacturing. Brushes are handmade in Germany at the da Vinci family owned factory since 1890.
