Add earrings to cart first, then add this option to have the existing hooks changed. If you need more than one upgrade of the same type simply change the quantity. If you are buying several pairs and need different hook upgrade styles for each, use the "Message" box in the checkout to indicate which upgrade goes on which pair (e.g. "sterling hooks on #E05, gunmetal leverbacks on #E33"). All hooks made in USA. Sorry, we do not sell hooks by themselves, they must be purchased as an upgrade on a pair of earrings.
Note: gunmetal hook options should only be used for gunmetal earrings since they are noticably black compared to other metals. Also, be aware that some gunmetal components may contain nickel.
