These finest quality Chingking bristle brushes feature interlocked construction using the highest quality Chungking bristle. This bristle is double boiled for extra spring and endurance. This process allows for a less stiff bristle that allows for maximum stroke control that is not possible with overly stiff bristle. These handmade brushes are hand shaped and stiffer bristles are removed to ensure better flags at the tips. Better flags distribute color more evenly than bristle that is simply cut flat at the end. The bristle is deeply set in the ferrule which is why Maestro 2 holds its shape and shed less bristles. These brushes are constructed with seamless, nickel-plated brass ferrules that are rust-resistant.
