Premium quality, heavy duty synthetic bristle will endure the heaviest paints and solvents. Connoisseur pure synthetic brushes will accommodate oil and acrylic color straight from the tube – from thick to thin. The interlocking fibers mimic the makeup of natural hog bristles, however, the synthetic filaments are sturdier than nylon – with the additional advantage of a better paint holding capacity. Brushes are guaranteed for life against defects in materials or manufacturing.
