Metal Type : 14K Solid Yellow Gold Country of origin : USA Product dimensions LxWxH (MM) : 14.9x18x3.5 Ring outside dimension (MM) : 11 Bar width (MM) : 18 The toggle bar of this 14-karat yellow gold toggle clasp features ball ends and has a smooth finish that complements a variety of jewelry designs. 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.
