Set of 2 Colineo da Vinci watercolor brushes For many years, the brush industry has invested in researching all options to imitate the special properties of the hair of the Siberian red sable with fibers synthetics. A very difficult task due to the particular structure of this precious natural material, which has become very rare and expensive in recent years. With the da Vinci COLINEO we have managed to create a mixture of synthetic fibers very similar to its natural form. A carefully balanced mixture of different lengths of straight and wavy synthetic fibers Sharp tip, extra fine and precise brush strokes High elasticity and color absorption Wooden handle Includes: Series 442 number 2 Series 5522 number 2
