The quality of this set is simply outstanding. The best materials, careful processing and attention to detail can be clearly identified. Unfortunately, the delivery took place in a plastic bag in a flat envelope. (It raises the question whether this jewelry - the original, after all, is expected to cost 140 - does not deserve to be delivered in a small padded jewelery box; which would certainly also still fit in an envelope). So both ear plugs were strongly bent at me and I had to send back (which was, after all free, thanks a lot!).
