This ELAN sew-on button is made for garment repairs, tailoring, and craft projects where you need a neat closure on shirts, sweaters, coats, bags, or costumes. Each retail card includes 2 button(s) sized 22 mm (7/8 in) with a shank-back design that adds clearance so layered buttonholes sit smoothly. Sew on by hand or machine with matching thread, secure the stitches on the back, and confirm buttonhole fit before washing, pressing, or dry cleaning.
