Classic four‑hole sewing button sized 20mm (3/4"), packaged 2 per card. Four holes allow crisscross or parallel stitching for extra security on high‑wear areas like coats, trousers and workwear. The flat profile sits smoothly against the fabric and is easy to replace or add to handmade projects. Attach by hand or machine for a strong, reliable closure that resists twisting and daily stress. Supplied on an ELAN notions card for convenient storage in your kit.
