These brushes are made to give superb results with today's water based paints and modern acrylic varnishes. The synthetic bristles are polyester filaments, tapered to give the best flow characteristics and minimise brush lines. The ferrule is stainless steel and the wooden handle finished with a clear lacquer. These brushes are just as effective when used with traditional oil based paints. Faithfull paintbrushes are manufactured to the highest standard using the very best materials. The bristles are bonded using top quality resin to avoid any shedding. All the handles are made from natural wood from renewable sources. The stainless steel ferrules are rustproof.
