ELAN two-hole sew-through button measuring 15 mm (5/8 in) in diameter, shipped on a retail card of 2. A simple, versatile fastener for shirts, cardigans, childrenswear and accessories, providing a neat, low-profile finish. Attach by hand or with a machine button-sew program; consider a small thread shank for thicker layers. Confirm placement and orientation before stitching so stress is balanced and the button sits flat without puckering.
