Classic ELAN shank button measuring 13 mm (1/2″) in diameter, supplied on a retail card of 4. The shank‑back design leaves the button face smooth while providing thread clearance, helping thicker layers button cleanly. Suitable for coats, knitwear, bags and costume work or for replacing lost buttons. Hand‑sew through the rear shank; test placement, buttonhole fit and thread tension so the closure moves freely without strain.
