Annie's 4-yard Zipper Chain with 16 pulls is perfect for multiple projects. You can use this zipper for large designs like backpacks and jackets or shorten them for purses, wallets, skirts, and more. These nylon zipper coils enable you to make single-slide or double-slide zippers of any length (up to 144") with little waste, saving money and time. Included with the 4-yards, you also get 16 extra-large, coordinated pulls that are easy to install. The #4.5 zipper is soft and flexible, and unlike other zippers with chunky, molded polyester teeth, these are easy to sew and won't break your needle.
