Use this ELAN shank button to replace or coordinate closures on jackets, cardigans, bags, uniforms, and everyday sewing repairs. The raised back creates clearance over thicker fabrics and plackets, and the card includes 2 buttons with a 18 mm (3/4 in) diameter for consistent matching. Stitch on through the shank with strong thread, knot securely on the wrong side, and test the placement against your buttonholes for a smooth, even finish.
