This 12/20 yellow gold-filled hollow toggle clasp is made from tubing, making it lightweight and comfortable. Featuring a twist-pattern design with button ends and a bright finish, the clasp 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. Gold-filled clasps deliver karat gold at a more affordable cost than solid gold, allowing you to design with the touch of precious metal customers look for and to offer your designs at a price customers appreciate.
