This ELAN 4-hole button set offers a classic sew-through closure for garments, bags, and accessories that need a stable attachment and a tidy finished look. Each card includes 2 buttons sized 15 mm (9/16 in), letting you create matching closures for repairs, alterations, or coordinated finishing details. Sew with a cross or parallel stitch, anchor the thread ends firmly, and follow the fabric’s care instructions to help the closure stay secure over time.
