Zippers by the Yard contain 4 yards of zipper chain and 16 color-coordinated extra-large pulls*. This packaging enables you to make single-slide or double-slide zippers of any length (up to 144″) with little waste, saving money and time. Here’s why we prefer these zippers: Dress and skirt zippers carried by most local stores are too small. The #4.5 size is just the right size for purses, bags, and totes. The wide zipper tape makes insertion easy. Unlike zippers with chunky, molded polyester teeth, these handbag zippers are soft and flexible, making them easy to sew through. (No more broken needles!) The nylon coil is strong and durable zip after zip.
