TierraCast® antique copper plated Claddagh toggle clasps. 16mm ring, 23mm bar. This is part of TierraCast's new Celtic launch taking us back to their origins. The Claddagh is a traditional Irish symbol that represents friendship, love and loyalty. Toggles are popular for bracelet designs, because they're easier to manipulate with one hand than many other clasp styles. TierraCast Safety Compliance Info.
