These ELAN 2-hole sew-through buttons provide a flat, classic closure for everyday garments, bags, and general sewing repairs. The pack contains 4 button(s) in 13 mm (1/2 in), a practical diameter for matching existing buttonholes on shirts, knitwear, and light jackets. Stitch securely through both holes, test placement on a fabric scrap for alignment, and follow your finished item care instructions.
