The premium version of the pins are the glass-head pins. They are characterized by a heat-resistant, round head made of high-quality glass. The glass heads are available in different colors, which you can easily see in the fabric after sewing the marked workpieces. Made of hardened steel, the smooth shaft of the needles has a well-balanced spring hardness, which means that it cannot bend or break. The fine tip penetrates easily through all fabrics and protects the fibers in this way. Prym offers the glass-head pins in lengths from 30 mm to 48 mm.
