ELAN 2-hole sew-through buttons are a simple closure choice for everyday sewing, mending, and garment construction. This card includes 3 buttons sized 18 mm (0.71 in), suited to shirts, blouses, and everyday mending when you want a flat profile that sits close to the fabric. Position the button to match the buttonhole, stitch securely with appropriate thread, and reinforce the back for items that will be washed often.
