ELAN 4 Hole Buttons are sew-through buttons suited to garment sewing, repairs, and accessories that need a classic four-hole look with a clean finish. This pack contains 3 buttons measuring 15 mm (about 5/8 in) in diameter, making it easy to match common clothing and craft projects. Choose thread weight and buttonhole size to suit your fabric, and stitch securely through all four holes to keep the button flat and stable.
