Hi -- I have a copper bracelet whose foldover fastener is not reliably secure, so I want to add a small copper safety chain. I need to be able to fasten the safety chain to the bracelet easily, not being mechanically inclined! so am thinking that spring rings would be easy to affix to the round thing that attaches the bracelet to its closure at either end. Have not been able to find anything like this, so hope it is appropriate for an Alchemy listing. Thanks! Kathy Gallagher
