ELAN shank buttons are a versatile option for coats, jackets, knitwear, and bags where a raised back helps the button clear thicker fabric layers. This card includes 2 shank-back buttons sized 18 mm (3/4 in), offering a clean face while keeping stitching tucked behind the button. Measure buttonholes and layer thickness before attaching, then sew with sturdy thread and secure knots to help prevent loosening over time.
