FixnZip® can repair zippers without needles, threads and tools. FixnZip is eco-friendly and can be taken off one item and used for another. The slider parts are made of nickel-plated zinc die cast, and the spring and thumbscrew are made of stainless steel. Available in small, medium and large, FixnZip can be used on a variety of items, including boat covers, bedding and clothing. If a zipper is missing some teeth, the FixnZip glides over these and realigns the remaining teeth, restoring the functionality of the zipper.
