This ELAN two-hole button is a straightforward sew-on closure for everyday garments, alterations, and quick repairs where a flat profile is preferred. In 12 mm (1/2 in) with 5 per card, it works well for shirts, blouses, cuffs, childrenswear, and light accessories. Stitch with standard thread, keep tension even so it lies flat, and confirm buttonhole size and placement before sewing for a tidy finish.
