ELAN button card sized 13 mm (1/2inch) with 4 per pack provides a reliable, easy-to-sew closure for everyday garments and accessories. The classic 2-hole sew-through design lies flat, feeds smoothly under a presser foot, and secures with straightforward stitches for a clean finish. Use on shirts, cardigans, skirts, light jackets, uniforms, kidswear, bags, and craft projects. Match diameter to existing buttonholes and test stitch length and tension on a scrap for consistent results.
