Durable shank‑back buttons sized 20mm (3/4") packaged 2 per card. A raised shank keeps thread hidden and lifts the button above the fabric, ideal for thicker cloth and layered garments. Use to replace missing buttons or add a polished closure to coats, blazers, knitwear, uniforms, bags and costumes. Attach by hand or machine using matching thread and secure knots on the wrong side. Test placement and spacing on scrap fabric for alignment.
