Durable 12 mm (1/2") four‑hole buttons that distribute stress across more threads for a robust hold. The classic 4‑hole layout is ideal for shirts, uniforms, cardigans and medium‑weight fabrics where a stable, balanced stitch is preferred. Use for replacements or to complete handmade garments with a tidy, reliable closure. Pack of 6 provides enough pieces for common garment plackets and extras for backups.
