We're so very sorry to learn your Swiffer Duster Refill with a Handle wasn't as you expect. It sounds like you may have confused our Duster with another kind, as our Dusters rest directly on the Handle, no hold pin needed. Fluff the Duster up by holding onto an end in each hand. Then, see-saw your hands up and down. By doing this, it'll open up the fingers, and allow more space for you to collect dust. On the back, you'll see two sleeves you can slide the handle into. After fully inserting the prongs. smooth out the sleeves, but make sure they're fully covering the prongs. This'll help keep your Duster on the handle. If you need further help, give us a call any Monday through Friday, from 9 AM to 6 PM, EST. Our number is 1 (800) 214-8734.
