Platinum spring ring clasps are round hollow tubes with a tiny coil spring inside and a jump ring attached for connecting to one end of a chain. A movable, spring-tensioned bolt has a lever attached; use your fingernail to push the bolt back to open the spring ring. The bolt is held firmly closed by the internal spring inside the tubing. It takes two hands to open and close a spring ring.\u003c\/p\u003e\u003cp\u003eThis 5mm Platinum spring ring clasp features an \u003cstrong\u003eopen top jump ring\u003c\/strong\u003e for easily attaching to one end of a chain.
