Classic 2‑hole sew‑through buttons for everyday garments, repairs and craft projects. The flat profile lies neatly on fabric and stitches cleanly for a reliable hold on shirts, sweaters and bags. Edges are smooth for easy handling and consistent feed under the presser foot. Choose the 13 mm (1/2in) size to match existing buttonholes. Each card includes 4 button(s). Test on fabric scraps to confirm needle, stitch length and tension.
