Da Vinci IMPASTO Top Acryl brushes are made of white synthetic fibres with interlocking effect bristles, medium length which are especially developed for impasto painting. Acrylic colours are used in a more liquid as well as thicker consistency and for special techniques you need painting knifes. The IMPASTO has been designed to be used with the many texture gels and pastes now available - it is the elastic painting knife brush. They are made according to certified green manufacturing with sustainable wood handles and rust resistant silver ferrules. Brushes are handmade in Germany at the da Vinci family owned factory since 1890.
