These hard-to-find nylon-coil zippers are perfect for bags and carriers. Here's why we prefer them: 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. The double slide lets you open your bag from either end. We stock these 30-inch double-slide zippers in 12 colors to help you find just the right color for your project. Note: Many of By Annie's patterns call for these zippers. It is actually easier to use zippers longer than needed as you can avoid the stops at each end. All of By Annie's patterns include complete instructions for installing zippers quickly and easily. We promise that these are the easiest zippers you will ever put into a project!
