ELAN 2-hole buttons are sew-through closures for garments, knitwear, and craft projects that need a clean, flat finish. This card includes 2 buttons in 25 mm (1 in), sized for repairs and new makes where consistent button diameter matters. Stitch through the holes with matching thread and add a thread shank if needed for thicker fabrics, then confirm fit with your buttonhole before sewing on all buttons.
