The Prym “Jersey” press fasteners are characterised by their fastening strength and are especially intended for thin and stretch fabrics. They are often used in baby’s and children’s clothing. The advantage of this press fastener is that no hole has to be punched for mounting - rather the integrated serrated ring only presses down the into the fabric. Washing, spinning, cleaning, ironing is no problem. The press fasteners are available in different colours and designs. The press fasteners can be mounted with the included tool or can be mounted with the VARIO pliers for non-sew products or the Prym tripod.
