ELAN shank buttons offer a clean closure option for apparel and accessories without needing a flat sew-through button on the fabric face. This set includes 15 mm (5/8 in) shank-back buttons for shirts, cardigans, and light outerwear details where a little clearance helps. Stitch through the shank with sturdy thread, confirm alignment with your buttonhole or loop, and secure with a strong knot for durability.
