The Size 1 Gainsborough Oil & Acrylic Round brush is made from Chungking hog's hair. This Professional-grade brush is generally the best choice for oil and acrylic paint due to the flags that hold color. The strong, durable brush easily manipulates heavy paint. It has a unique taper that causes the bristles to interlock, which maintains its original shape and helps control the placement of color. Rounds have a round ferrule and the tip is round and slightly pointed. They are designed for creating very controlled brush strokes and details. Since 1905, Grumbacher has been a brand trusted by students, professors, art conservationists, and professional artists throughout the United States.
