For Watercolor and Acrylic: Curry's flat watercolor brush utilizes synthetic fibers for economy in these large sizes. None the less, it performs exceptionally well, is very responsive, and can produce very clean strokes. It is also durable enough for most other types of paint. The ferrule is made of seamless nickel and the beveled handle, made of strong clear acrylic, is an additional tool for scraping. Clear handle, Synthetic dyed fiber, Bright Shape, Short Handle.
