Just about everything was wrong with this purchase.  The one ball was dented and then I had trouble screwing the back in to put it back on the card.  There is no way you could screw these in your ear lobes!  So I used the return option and there is no prepaid label - I have to go into the post office and have it weighed and send myself.  hassle after hassle on this.  I am making note of the manufacturer to not use again.
