P029139 Prym Glass-headed pins are heat-resistant, round headed and made of premium glass. Available in various colour versions, which you can recognise in the fabric after sewing the pinned work pieces. The pin's smooth stem, made of hardened steel, has balanced spring stiffness, and as a result, it cannot bend or break. Its fine tip easily penetrates any fabric, thereby going easy on the fibres. 029139 asstd 0.60 30mm 40pc
