The ELAN 4-hole sew-through button provides a stable closure for garments, mending, and everyday craft projects in wardrobe upkeep. Each card includes 3 button(s) sized 15 mm (9/16 in), suitable for trousers, coats, uniforms, cardigans, and accessories that benefit from balanced attachment. Use a balanced stitch pattern across the holes, knot securely on the underside, and check placement on a scrap so the button sits flat without twisting.
