This full-bodied fiber brush whisks away dust and lint naturally, without radioactivity. A special blend of natural hair and conductive fiber is carefully hand sewn with stainless steel wire. The resulting high-quality brush is soft, gentle and safe to use on sensitive materials such as lenses, film and computer screens. The static is simply drained off by the conductive fiber while the natural blend of fine goat hair whisks away the dust. Maintenance is simple and easy. The easiest way to keep your StaticWisk clean is to vacuum the brushes to remove built-up dust and dirt. Because the StaticWisk brushes are hand sewn with stainless steel wire, they can even be washed in shampoo and water.
