ELAN 4-hole sew-through buttons provide a classic look for everyday sewing, mending, and garment finishing on light to medium-weight fabrics. Packaged 2 per card, each button measures 20 mm (3/4 in) in diameter and suits shirts, uniforms, jackets, bags, and craft projects. Choose a stitch pattern that matches your fabric weight, and test placement and spacing on a scrap to keep the closure aligned and secure.
