50mm Oval Sunglasses

I was so excited to see these come back in stock, I tried them on in store and wanted to think about it- then they sold out and were impossible to find for a month. What I was sent I can almost guarantee was a knockoff pair of sunglasses. The packaging seemed flimsy- and the glasses came in a plastic bag. There was no paperwork/ booklet/ authenticity card included, and the glasses themselves did not feel like they were great quality. I have other mui mui glasses and these were definitely not up to the same standards. I am just so disappointed because normally Nordstrom has great quality control.
