Swiffer Dusters pick up dust and lock it away with thousands of flexible, fluffy fibers and now it features an improved handle that extends three feet, making it easier to clean hard-to-reach places. The fibers that make up this Swiffer Duster are lightly coated with Dust Lock Adhesive and change shape to reach into tight spaces, trapping up to twice as much dust than a dry dust cloth, leaving it sparkling clean. The Extender Handle that comes with this duster has a handle that pivots and locks into four different positions. Each position tackles a different cleaning challenge such as angled surfaces, ceiling fans, wood furniture, cabinet corners, baseboards and crown molding. 6 per box, 4 boxes per case
