Made from 304-grade stainless steel, this toggle clasp set features a round tubing design and has flat ends on the bar. A toggle clasp is a two-part clasp consisting of a ring and a bar. The bar end requires a short length of chain to allow it to slide lengthwise through the ring, then turn sideways so that it cannot fit back through the ring, effectively closing the jewelry piece. To open, the bar is simply pulled further through the ring just far enough to allow it to turn lengthwise again and slide back through the ring.
