ELAN shank button in 15.0 mm (9/16") comes carded 3 per pack for quick repairs and clean finishing. The raised rear shank protects stitches and leaves thread clearance so thicker layers fasten smoothly and garments drape neatly on coats, knitwear and structured bags. Hand‑sew with strong thread; match the diameter to existing buttonholes and test placement on a scrap to confirm spacing, movement and alignment.
