Our sheet clips can perfectly transform a flat sheet into a well - fitting fitted sheet, and they're also suitable for flat sheets or bedspreads. Our sheet fasteners can be easily machine - washed and dried at low, medium, or high speeds. 2. Durable Sheet Tighteners Our sheet tighteners can fit any existing sheets you have.
