1. The already mentioned some customers: the closures are loose. But it was no problem for me, just have a couple of other retrieved from my collection, give the pretty jewelery firm grip. 2. The earrings are not worked symmetrical - so both identical. Actually, they need to be mirrored for the perfect look. But that probably will not fall into the eye, as it seems to have been just struck me. Otherwise, I like them extremely well.
