I'm hoping to get your ladies' insight on this matter since this is my first Chanel purchase. I recently bought the M/L classic flap from the Beverly Hills Chanel boutique, and upon closer inspection at home, I found the lock to be a bit askew. I went back in to exchange it for another bag. This time the lock is nice and straight, but I found a thread hanging out and a light 2 inch scratch. I still have 10 days left to exchange or return it. Before I go in, I wanted to ask if there are any other things that I should be wary of that maybe some of you have experienced in terms of defects and quality control. Hopefully the third time is the charm. Thank you in advance!
