This ELAN four-hole button offers a classic, flat sew-on closure for apparel, uniforms, and accessory projects that see regular use. The pack provides 3 buttons sized 18 mm (3/4 in) for shirts, trousers, knitwear, and repairs where a neat, centered attachment is important. Use a cross or parallel stitch for secure hold, pull thread tension evenly, and check spacing against the original buttonhole placement before finishing.
