These Microfiber Static Duster are produced with Microfiber and Polypropylene blended synthetic fibers and include a plastic extension handle that allows the product to extend from 28" to 40" in length. The total fiber head length is 11" and is produced with a flexible wire core that allows the head to be bent around objects for better cleaning. Perfect for tight cleaning areas like blinds and keyboards where the soft fibers can attract the dust without scratching or damaging the surface. With the Microfiber filament these dusters grab and hold dust far better than traditional static dusters. Prices are per individual duster unit. Packaging of orders less than bulk quantities will be packaged according to the order.
