Da Vinci's "Maestro" designation is reserved for brushes manufactured using male winter Siberian Kolinsky Red Sable fur. These are top-of-the-line, high quality brushes.
The extra sharp, needle-like point and longer tapered hair length result in faster action at the tip and the tightest snap at the point. Expect superior spring and control, plus unsurpassed water-carrying performance.
All brushes have plated brass, seamless ferrules.
