Traditional 2‑hole sew‑through buttons for everyday garments and craft projects. Pack contains 4 button(s) sized 13 mm (1/2 in). The smooth, low‑profile shape is easy to sew and sits flat for a neat finish on shirts, blouses, knitwear and kids’ clothes. Useful for mending and replacing lost buttons or adding a simple closure to handmade pieces. Sew by hand or machine; match thread to fabric and consider a dab of fray preventer on buttonholes for durability.
