For many years, the brush industry has invested in researching all options to imitate the special properties of Siberian Kolinsky Red Sable hair with synthetic fibers. A most difficult task due to the particular structure of this precious natural material, which has become very rare and expensive over the last few years. With COLINEO we have succeeded in creating a mixture of synthetic fibers, very similar to its natural ideal. A carefully balanced mixture of different lengths of straight and wavy synthetic fibers with extra fine tips and tapered points, high elasticity and color absorption. Made in Germany. 100% Vegan. Handles are from sustainable forests in the Baltic states. Eco friendly manufacturing. This set includes: Series 442 Size 2 and Series 5522 Size 2. Recommended age 2+ years
