Hi ladies! I was wondering if someone could give me advise on my new celine box bag which I bought pre loved. Is it normal for leather at the back (which I assume is bent a lot from the bag opening and closing) to get hard and cracked. I see it happening on one side of the bag (attached pictures) but the leather is still smooth on the left side. I’ve barely used the bag and because the leather is delicate I’m worried of causing more damage. What do you guys think?
