The Maestro white bristle brushes are hand built and interlocked by skilled brush makers with the highest quality materials. They are best suited for oil and acrylic painting and the versatile filbert shape combines the advantages of flat and round brushes. Properly cleaned after each use the brush will retain this shape even after long use and many washes. They are made according to certified green manufacturing with sustainable, natural polished wood handles and rust resistant ferrules. Brushes are handmade in Germany at the da Vinci family owned factory since 1890.
