This ELAN two-hole sew-through button provides a dependable closure for everyday sewing, mending, and garment finishing. Each card includes 2 button(s) sized 30 mm (1 1/8 in) that lie flat and stitch on cleanly by hand or machine for shirts, knitwear, and accessories. Match the diameter to your buttonholes and use a fabric scrap to check stitch length and tension for a neat, durable result on high-wear closures.
