Classic ELAN shank button measuring 30 mm (1 1/8″) in diameter, supplied on a retail card of 1. 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.
