The Prym press fasteners "Jersey" are characterized by their light to medium closing force and are specially designed for thinner and stretchable fabrics - as often used in baby and children's clothing. The advantage of this snap fastener is that no hole needs to be punched for attachment - rather, the integrated serrated ring simply displaces the fabric, thus protecting it. Washing, spinning, cleaning, ironing, mangling: no problem for the rust-free press fasteners "Jersey" from Prym.
