A feather duster is a cleaning tool that is typically made from a wooden dowel handle onto which feathers are wound with a wire. The feathers are most often 14 to 32 inches (36 to 81 cm) long. Some dusters have a retractable casing instead of a dowel handle and these are typically used by rack-jobbers and truck drivers who need to clean store shelves, and can retract the feathers into the handle to avoid damage.
Feather dusters serve the same function as soft brooms or brushes, except that they are only meant to remove loose superficial dust from delicate surfaces (such as paintings and papercrafts) or around fragile items (such as porcelain and glassware). They are effective in cleaning tight areas, or areas where there are many odds and ends. The individual feathers are flexible and can reach into gaps and crevices without disturbing the surrounding, and the tiny barbules on the feathers themselves that act as "fingers" to collect and remove dust particles.
