I received my Stella from the eBay buyer today. It's GORGEOUS but there is a slight problem. One of the metal rivets (on the strap) is not anchored and simply pops off. If it were a used bag or if she would have said something, I guess I wouldn't be so disappointed...but it's brand new and I paid over $750 for it. That's A LOT of money for something that isn't perfect. Is this an easy fix? Should I email the seller? What do I say? I don't know if she even knew about it. :wondering Thanks for any advice.
