Developed by da Vinci brushes in Germany, Casaneo is the latest breakthrought in synthetic brush making. In 1983, da Vinci invented the multi diameter synthetic brush with their best selling Cosmotop Spin line of watercolor brushes. Casaneo uses a new "wavy" or "crimped" fiber that yields stunning results. Excellent for watercolor, gouache, acrylic, silk painting, calligraphy, with ink and for sketching, Casaneo is like no other synthetic brush. A favorite brush of the Urban Sketchers movement.
