Animal hair brushes are tools used for painting, makeup application, and other artistic endeavors. They are made from the hair of various animals, such as sable, squirrel, and hog. These brushes are valued for their softness, flexibility, and ability to hold paint or other mediums effectively. The type of animal hair used affects the brush's performance. For example, sable hair brushes are known for their fine points and smooth application, making them ideal for detailed work. In contrast, hog hair brushes are stiffer and better suited for applying thicker materials.
