ELAN shank buttons provide a polished, raised-back fastener for coats, cardigans, knitwear and structured accessories. Each retail card includes 2 button(s) sized 15 mm (5/8 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.
