Prym's sew-free press studs make it easy for you to create neat, solid, professional-looking closures for garments, accessories and crafts. Suitable for thin jersey and lightweight fabrics, these press-studs from Prym have a light closing force - ideal for baby clothes and children's clothing, for example. With the jersey snaps, there is virtually no risk of jersey or other thin knit fabrics laddering. Attach the snaps with the included tool and a hammer. Or with the Prym vario pliers.
