This ELAN sew-through 4-hole button is a reliable choice for garments and accessories that benefit from an even, stable attachment. The 15 mm (9/16 in) size and four-hole layout support cross or parallel stitching, and each card includes 3 pieces for replacements or new makes. Confirm diameter against your buttonholes, keep stitch tension consistent, and reinforce on heavier fabrics to reduce wear at the closure point.
