The Icon Brush has an angled head that lets you effectively brush corners and crevices that are sometimes hard to reach with a normal brush, and the ergonomically curved handle keeps you from scraping the skin off your knuckles as you brush. At 12,700 bristles per cm³, this is the highest density that we know of. The Icon Brush is made from sustainable and biodegradable materials, which means maximum removal of chalk and grease from holds in an eco-friendly product.
