This ELAN shank button card is designed for quick replacements and clean closures on garments, costumes, and accessories. The card includes 4 buttons sized 8 mm (1/4 in) for sewing onto shirts, knitwear, outerwear, bags, and craft projects; It suits both new makes and simple repairs. 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.
