Durable, no‑sew cap snaps for creating professional closures on garments and accessories without stitching buttonholes. The 11.5 mm (½″) diameter is a popular size for shirts, baby items and light outerwear. Use a compatible snap setting tool to secure components firmly through fabric layers for a clean, ready‑to‑wear finish. Test on a scrap first and adjust stitch length and tension for best results.
