Floss Winder: This tool is useful for winding cord that doesn't come on a spool so you can keep the ends under control. It comes with a cardboard spool that attaches to the winder. The winder is designed to sit on any standard compartment tray for stability. You just wind the handle and the spool turns as you hold the cord with your other hand so the cord ends up neatly wound on the spool for future use.
