series 170, also known as Micro Nova, is a specialized line of extra-fine synthetic brushes designed for high-precision detail work, and high valued by modelers from all over the world. They are made from the finest synthetic fibers, pointed round with a needle type tip, specifically developed to retain its shape even after prolonged use, to mimic the elasticity of natural Kolinsky sable. The red belly bandage is a signature feature giving a 170 instant recognition and the handle is exagonal to prevent rolling and provide maximum control.
