ELAN button card sized 19 mm (3/4inch) with 2 per pack provides a reliable, easy-to-sew closure for everyday garments and accessories. The traditional 4-hole layout spreads stitch tension evenly, producing a durable hold and a tidy, balanced finish that lies flat under a presser foot. Use on shirts, cardigans, skirts, light jackets, uniforms, kidswear, bags, and craft projects. Match the diameter to existing buttonholes and test stitch length and tension on a scrap for consistent results.
