The Prym “Jersey” press fasteners are characterised by their easy to medium fastening strength and are especially intended for thin and stretch fabrics, as 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 fabric so that it is protected. Washing, spinning, cleaning, ironing, mangling: for stainless “Jersey” press fasteners made by Prym, this is no problem. The press fasteners are available in different colours and designs. The 18mm size press fasteners can only be worked on with the included tool however the 10 and 12 mm sizes can be worked on with the VARIO pliers for non-sew products or the Prym tripod.
