A flat Richeson “Signature” bristle oil brush, Size 20, and Richeson’s “Signature” line is among the best in the world. Created from high quality bristles that are carefully set to perfection in bright and shiny polished ferrules. The bristles in these brushes are superior in quality and the lacquered handles are easy to work with for artists of all skill sets and backgrounds. This is the perfect addition to any veteran artist’s set of brushes. Flat brushes have longer hair out and they carry more paint. Because they carry more paint they can be harder to control and may be a better option for experienced artists in some cases.
