For Watercolour and Acrylic: Curry's flat watercolour brush utilizes synthetic fibres 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 bevelled handle, made of strong clear acrylic, is an additional tool for scraping. Clear handle, Synthetic dyed Fibre, Bright Shape, Short Handle.
