The ELAN 2-hole sew-through button is a versatile notion for clothing, craft projects, and routine mending where a simple flat button is preferred. Each card includes two buttons in a 25 mm (1 in) diameter, sized for many outerwear and accessory closures and easy to stitch on by hand or machine. Check your buttonhole size before sewing, then secure with matching thread tension so the button sits flat and comfortable.
