ELAN Shank Button provides a clean, reliable closure for everyday sewing and wardrobe upkeep, sized at 15 mm (9/16"). Each card includes 3 pieces; the low-profile design suits shirts, knitwear and light outerwear, and works for replacements, repairs or finishing new makes on garments, bags and simple craft projects. Hand or machine-sew with matching thread, check buttonhole fit before stitching, and reinforce stress points as needed for a durable result.
