Brass, rustproof, non-sew press fasteners with medium fastening strength. These fasteners are designed for anorak jackets but can be used on many different types of fabric, clothing, and accessories. The pack includes a tool for application, though using Prym Vario pliers is recommended to simplify and speed up the process. Suitable as closures for non-elastic fabrics, they offer medium closing force and are ideal for skirts, jackets, coats, or dresses. Can be used with the appropriate pliers or with the prym.ergonomics tripod.
