Prym's pin assortment has these 0.4 mm fine glass-headed pins for pinning work on fine fabrics. The pin's smooth stem, made of flexible spring steel, has ideal usage flexibility, which prevents it from bending or breaking. Thanks to its finely-polished tip, the pins also penetrate through the finest of fabrics without harming the fibres. Its heat-resistant glass head in the signal colour red makes these pins ironable and well-visible. This ensures that no pins remain in the clothing. The plastic canister contains 5 grams of the super-fine, glass-headed pins.
