This ELAN sew-on shank button adds a clean closure to garments, knitwear, and small accessories where you want the stitching hidden on the back. The card includes 2 buttons sized 25 mm (1 in), suitable for repairs or matching closures on shirts, cardigans, cuffs, and light outerwear. Sew through the rear shank with strong thread and reinforce stress points; check buttonhole fit before stitching and protect the button from direct heat when pressing.
