Shank-back buttons sized for coats, cardigans and structured garments. The raised shank protects thread and allows the button to sit above thicker fabrics for a smooth drape. Smooth edges aid handling and provide a professional finish on jackets, knitwear and handbags. Select the 17 mm (5/8in) size to match your buttonhole and seam details. Each card includes 3 button(s). Test placement on fabric scraps and reinforce with interfacing as needed.
