Refill dusters are designed to fit on Swiffer 360-Degree Dusters to clean your home and office. Thousands of fluffy fibers with Dust Lock Adhesive in an all-around design clean deep into grooves to trap and lock up to three times more dust than a feather duster. The unique flexible fibers can also change shape to get into nooks and crannies and dust virtually any surface for a great clean. All-around design has 50 percent more fibers than regular Swiffer Dusters, allowing it to lock dust away for good. Disposable dusters can be used virtually anywhere and fit into tight spaces. Handle for these unscented dusters is sold separately.
