ELAN two‑hole sew‑through button measuring 20 mm (3/4″) 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.
