The bristles of our Waxing Brushes come from the hair of the finest Shanghai Bristle from the cutest little boars in China. The ferrule is made with nickel plated steel for rust resistance. We recommend cleaning your wax brush with a low odor Mineral Spirits. Wipe clean with a soft rag. Do not use soap! The bristles of our Buffing Brushes are a horse hair / synthetic blend; strong enough to buff and burnish, soft enough to prevent scratching. Our New(ish) Comfort Handle Wax / Stencil Brushes have the perfect mix of natural and synthetic bristles for that perfect pounce and a tapered handle for a comfortable grip.
