Shank‑back button sized 20 mm (¾ in), ideal for lighter outerwear, cardigans and accessories. The integrated shank creates room for fabric and helps closures lay smoothly without puckering. Includes one button for a single replacement or accent closure. Select a finish to coordinate with trims and lining for a refined, consistent appearance in new makes or mends. Confirm the size and pack quantity before sewing to ensure proper fit and finish.
