This ELAN shank-back button adds a clean, slightly raised closure for coats, cardigans, knitwear, and accessories where extra thread clearance is helpful. Each card contains 3 buttons in 15 mm (5/8 in), designed to sit off the fabric so thicker layers fasten smoothly without stressing the stitches. Sew through the rear shank with strong thread, consider a backing button on heavy fabrics, and follow your garment’s laundering or dry-cleaning instructions for best results.
