This type of brush hair comes from hogs in different parts of the world, but the very best comes from China. Hog bristle is different than any other natural fiber, since it forms a V-shaped split or "flag" at the tip and has a natural curve. This gives it a resistance to fraying and it spreads paint smoothly and evenly. These brushes are great for any sign painter, or hand painter for outdoor work. The brushes are available in sizes 1" - 3", they have graduated hair lengths and most brushes are 5/16" of an inch, except for the 3" version that has a thickness of 3/8".
