These professional grade brushes feature a perfect blend of nylon and solid polyester filaments. This filament blend allows the brush to pick up and carry the heavier Paint + Primer paints and stains on the market while also providing soft, chemically tapered angled filament tips for excellent cut-in around trim and in small spaces and an ultra smooth finish without brush marks. Smooth sanded Beechwood handle fits comfortably in the hand during long paint projects.
