This ELAN shank button set provides a classic sew-on closure for garments and accessories that benefit from a button with a raised back. Each card includes 2 shank buttons with a 20 mm diameter, sized for repairs and replacements on outerwear, knitwear, bags, and costume pieces. Sew through the shank with strong thread, and verify the finished buttonhole or loop fit and placement before stitching on the garment.
