I bought her small earrings Silver secondary pair for my daughter who was about to return to school and who also tend to win without the express fasteners her curls in gold. I thought that at this price, I would have hurt less if lost. Well six months later, my daughter wear them almost every day and no allergic reactions, it does not blacken, do not twist, and fasteners hold very unlike his pair Gold! Anyway I am very happy and I'll take him to other models for her birthday soon.
