This ELAN back-shank button is designed to sit slightly above the fabric, giving clearance for thicker layers and structured seams. It measures 15 mm (5/8 in) in diameter and comes 2 per card, making it practical for coats, jackets, cardigans, and decorative closures. Sew firmly through the shank with strong thread, add a backing button on bulky fabrics if needed, and check buttonhole spacing before final placement.
