Glass Head Pins hold fabric layers together when patterning, basting and cutting prior to sewing. The 1-1/8-inch shaft length is a great length for general sewing projects. Pins are made from premium-quality, nickel-plated steel, meaning the pins are strong and won't bend out of shape easily. The glass heads are not affected by a hot iron. The pins come in a traditional plastic pinwheel organizer. We do not recommend sewing over pins as they may cause a needle deflection. Quantity: 40 pins.
