The S9 open-end zip fasteners are specifically designed for for knitwear and woollen cushions. The in part loosely woven tape makes it easy to either sew the zip onto knitwear or to knit it with the wool directly. They can be used as replacements for damaged zip fasteners and of course, for your own creations. These zip fasteners have an Oeko-Tex certificate and are available in a range of colours and lengths in an self-service box.
