Item description according to supplier: BOHIN glass head pins are ideal for classic sewing work. This diameter makes it possible to work on the widest variety of fabrics. The glass head will allow you to better identify the location of your pins. As glass does not melt under the soleplate of the iron, it will allow you to assemble your fabrics, mark your folds and hems. Made of hardened and nickel-plated steel, these pins will not twist below 40° c and will not oxidise.
