Grigio Synthetics by daVinci: for acrylics, oils and water-mixable oils. This is a breakthrough in synthetic brushes from daVinci, featuring a new fiber blend developed over years of research for oil and acrylic. Different diameter, slightly textured fibers are finely assembled to guarantee color absorption, strength and high elasticity. Fitting between a sharp synthetic and smooth kolinsky, Grigio gives the artist multiple benefits. Easy to clean.
