Alloy-Plastic Round Head Sewing Pins 4mm

These 4 mm (0.16 inch) sewing pins are built with an alloy-plastic composite body — combining the tensile resilience of metal with the surface softness of engineered plastic. Each of the 600 pins features a fully rounded head for comfortable handling and immediate visual recognition. Supplied in a single box with no mixed sizes or shapes, the uniformity supports repeatable results in technical applications such as block alignment in patchwork or grain-line marking in tailoring. The pins function effectively on natural fibres like wool and linen, as well as synthetic weaves including polyester and rayon — maintaining hold without compromising drape or finish.
