Shank-back buttons sized for coats, cardigans and structured garments. The raised shank protects thread and lets the button sit above thicker fabrics for a smooth drape. Clean edges aid handling and provide a professional finish on jackets, knitwear and handbags. Choose the 10 mm (3/8in) size to match your buttonhole and seam details. Each card includes 3 button(s). Test placement on fabric scraps and reinforce areas with interfacing if needed.
