Loft shiny silver tone dangly earrings, pre-owned but never worn

This is a pair of Loft Pre-owned (by me) silver tone earrings. I do not know what these earrings are made up of but appears to be a lighter weight metallic like material. I bought the earrings but never wore them. They are very shiny and seem lighter in weight than many “danglers” (see scale for weight of one earring). I have included photos of length, width, post length. They are stored in my nonsmoking home.
