This ELAN shank button card is designed for quick replacements and clean closures on garments, costumes, and accessories. The card includes 3 buttons sized 15 mm (5/8 in) for sewing onto shirts, knitwear, outerwear, bags, and craft projects. Sew with matching thread, anchor the stitches on the underside, and reinforce stress points so the button sits securely and looks finished after repeated use.
