Classic ELAN shank button measuring 18 mm (3/4 in) in diameter, supplied on a retail card of 2. The shank-back construction preserves a smooth button face and adds thread clearance so thicker layers fasten neatly. Use on coats, knitwear, bags and costume pieces, or as a durable replacement on ready-to-wear. Hand-sew through the rear shank with strong thread and test buttonhole clearance to ensure the closure moves freely without strain.
