Shank‑back buttons sized for coats, cardigans and structured projects. The raised shank protects thread and allows the button to sit above thicker fabrics for a smooth drape. Edges are smooth for easy handling and a professional look on jackets, knitwear and handbags. Choose the 10 mm (3/8in) size to match your buttonhole and seam details. Each card includes 4 button(s). Test placement on fabric scraps and reinforce with interfacing where needed.
