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 9 mm (3/8 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 5 button(s) for matching sets or reliable spares.
