The Da Vinci Maestro Series #35 has an extra long and pointedly shaped hair (similar to what brush makers call a "designers" or "animators" shape) that is made of pure Siberian Kolinsky red sable hair from selected male winter tails. The black handles are approx. 8" in length and have a shape that Da Vinci calls "esagonal", that means it's sort of triangular in basic shape, but highly rounded on the tips of the triangle forming a kind of hexagon shape. The hair is set in nickel plated brass ferrules. These brushes are sized using standard English sizes.
