Shank-back sewing buttons sized 13mm (1/2"), 4 per card. The raised shank keeps stitches hidden and allows space for thicker fabrics so closures fasten smoothly and garments drape cleanly. A versatile option for coats, jackets and knit garments as well as accessories and costume work. Use to refresh closures or add a neat, low-profile finish wherever a shank button is preferred. Supplied on an ELAN notions card for convenient storage in your kit.
