ELAN button card sized 23 mm (7/8inch) with 2 per pack provides a reliable, easy-to-sew closure for everyday garments and accessories. A traditional 4-hole layout spreads stitch tension evenly for a durable hold and a tidy, balanced look. 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.
