Durable shank‑back buttons sized 23mm (7/8") packaged 2 per card. A raised shank hides thread and lifts the button above the fabric, ideal for thicker textiles 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 with matching thread; secure knots on the wrong side and test spacing for consistent alignment.
