12.6mm Plain Round Toggle Clasp with 18.2mm Bar with Loop. You will need to attach our 6mm 21 Gauge Jump Ring to the round ring in order for this toggle to work properly because it does not have a loop like a traditional toggle clasp. We opted for the ring to have no loop for a cleaner more modern look. These toggles are available in multiple finishes and are lead safe, nickel-free hypoallergenic. They also have a durable layer of e-coating to protect the finish.
