ELAN shank buttons are classic sew-on closures for repairs and new makes on coats, jackets, knitwear, and bags that benefit from a raised back. This card includes 1 button sized 20 mm (3/4 in), with a shank that helps the button sit above layered fabrics for smoother fastening. Hand sew through the shank with strong thread, and confirm fit with your buttonhole or loop before finishing the final stitches.
