Durable shank‑back buttons sized 16mm (5/8") packaged 3 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; secure knots on the wrong side and test spacing for alignment.
