That was me but I changed my mind.I should go back for a second look at the pics above. I didn’t see spine cracking on the kelly above or stress on the shoulder pads attaching the rings. I think someone mentioned the peeling could be due to moisture.
Humidity will break down leather sooner but @pinke said the leather was fine elsewhere. Just need to point out for others who don't know, Pinkie didn't do this to the bag.
It could be a combo of the two, but the point is, even if a bag doesn't look as bad as this one, that's what someone is going to their bag in the long run if they carry the bag open. The stress is intense on those stress points.
