Classic shank‑back buttons add a subtle lift so fabric drapes smoothly without pulling at the stitching. The raised shank protects thread from friction and helps thicker layers close neatly at cuffs, plackets or bags. At 13 mm (1/2 in), the size works across coats, knitwear, shirts and costumes. Each piece is cleanly finished for snag‑free handling and a polished look. The card includes 3 button(s) for matching sets or reliable spares.
