ELAN’s classic 2‑hole sew‑through buttons offer a clean, versatile fastening for everyday garments and accessories. This card includes 4 13 mm (1/2") button(s) that lie flat and stitch on quickly by hand or machine. Use them for replacements, new projects or mending—ideal for shirts, knitwear, uniforms and bags. For best results, match the button diameter to your buttonhole and test on a fabric scrap to confirm spacing, stitch length and tension.
