Kalish Series #1 Kolinsky round brushes are made from pure Kolinsky sable. They are not only an excellent price, but also perform very well, making them our most outstanding value. These brushes are made in a small factory in Ireland by master brush makers using only the finest Kolinsky hair (60%male / 40%female). After careful preparation of the hair, the brushes are created by hand so that each brush develops a needle point, crisp snap and resiliency. The black lacquered handles are approx. 8" in length and have seamless nickel plated brass ferrules.
