It’s definitely not wear and tear! Many mono bags produced between 2013-2015 had bubbling and peeling issues. If you do a search you’ll see plenty of posts. Last year I purchased a pre-loved Delightful - totally forgetting about the peeling issue - and sure enough mine started peeling like crazy! I’d wipe it down but the white stuff kept coming back. One SA tried to say it was the wipes that did it but that bag had it before I tried to clean it. Take it into LV- it’s a known issue.
oh yes, so did they grant you a exchange or credit ?
