Series 35 has an extra long taper at the tip. The unique taper is great for fast, loose watercolor painting and is a favorite amongst illustrators, cartoonists and animators. Great for drawing long, clean lines. The Maestro designation denotes the highest quality winter male Kolinsky Red Sable hair from the Tobol River region in Eastern Siberia. All brushes are handmade from raw material to finished brush by skilled artisans at the da Vinci factory in Germany. A favorite of watercolorist Charles Reid. Sizes 000 to 24.
