It's not easy making a well-made fiberglass brush. A good brush has to be well-balanced for the right “feel”. It has to be able to be twirled without filaments “flying around” like a snow storm. It has to have a very generous filament cluster at just the right length to retain just the right amount of powder. Lastly, it needs to be made from the finest quality fiberglass filaments so that it “breaks in” like a new pair of jeans rather than breaking down, for soft non-abrasive results. Our fiber duster includes a blue-tinted polymetric balanced handle, a perfect hemispherical cone-shaped trim, the hand-twirled break-in process and the protective dust-free plastic container. 7” overall.
