Trekell’s Protégé line is an ingeniously engineered synthetic alternative to Kolinsky sable-hair, a classic brush filament known for its retention and performance properties. These brushes are on 6" short, black and silver handles. The Protégé round brush has inherited those traits, boasting the same thirsty belly and insanely sharp point as its ancestor. The big difference is the increased durability. So, while those old, expensive hairs are increasingly harder to come by, a Protégé will always be there for you.
