These are absolutely stunning! I ordered a pair for myself & when I got these I was blown away by the quality & sparkle! The entire circle, the chains to the tear drop ends are covered in crystals! They a silvery metal on the reverse side & only came with a thin double sided tape to stick them on with. I tried out my pair & they stayed on until I wanted them off. They're reusable if you use double sided body tape or "butt glue". I can not get over just how much these sparkle! (💎)(💎)
