Heart dangle earrings with heart design in the middle. The backings are made of typical craft store metal earring wire so they should not turn your skin green and they should be hypoallergenic. These unique charms were thrifted so I am not sure of the type of metal its made with. The jewelry has been sanitized as well. Message me with any questions!
