200Pcs Chain Extender for Jewelry Making, Silver and Gold Extension Tails for Necklaces, Bracelets, Anklets, Key Chains - Removable

I use these extension for making earrings. The items sold quickly will order again. I haven't noticed any discoloration, no complaints from customers. Will let you know if anyone complain. I understand these are not the most expensive but they are pretty good for the money.

good for necklaces

These are quite fine loop chains, but good choice of colours and loops not split so little chance of accidentally coming apart when jewellery worn
