Shank-back buttons from ELAN sized 13mm (1/2 in) for garments and accessories that need a little stand-off. Each card includes 2 button(s). The integrated shank lets the button sit above thicker layers and reduces abrasion on fabric, so closures slide easily and wear well. Attach by hand with strong thread for a secure hold. Ideal for coats, cardigans, bags and structured pieces. Match size to your buttonhole and reinforce stress points where needed.
