Add vintage style and cool dimension from this antique brass-plated pewter square swirl design toggle clasp. Made from lead-free pewter, this large jewelry clasp has two partsÂ—a loop and a bar. The loop portion is shaped into a geometric square, detailed with a swirl pattern with a wide open center. The bar portion features an elongated oval shape, stretched with pointed ends and a smooth front surface. Both parts display a detailed front surface and a concaved back side, and both display a weathered brass color.
