A non-separable zipper, also known as a skirt or pillow zipper, is a type of zipper that cannot be completely taken apart. Unlike divisible zippers, where the two strips of teeth can be completely separated from each other, the last teeth of a non-divisible zipper always remain attached to each other.
These zippers are often used in making skirts and cushions because they are smooth and thin. They provide a simple and effective way to close a skirt or pillow.
Non-separable zippers are available in different lengths and colors, so you can choose a zipper that perfectly matches your design. These zippers are also called spiral zippers.
Whether you are making a skirt or a pillow, a non-separable zipper is a handy and practical solution to provide your creations with a properly functioning closure. With the wide choice of options you can easily find the right zipper for your specific project.
