ELAN shank buttons provide a polished, raised‑back fastener for coats, cardigans, knitwear and structured accessories. Each retail card includes 1 button(s) sized 20 mm (3/4 in), and the rear shank creates thread clearance so thicker plackets and layered fabrics lie flat without puckering. Sew on by hand or with a machine button program, then test placement and reinforce stress points to ensure a secure hold through wear and laundering.
