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 4 button(s) sized 14 mm (1/2 in) with a 2-hole sew-through design that stitches flat to fabric for a clean finish. 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.
