I would suggest a purse organizer so that all items stay in place instead of rubbing against each other. Also keys and coins should belong in its own pouch if possible. They are magnets for dirt and quite harsh on leather items when in direct contact.
I was JUST thinking of posing this exact question. Thanks for posting it first!
I am considering a BV zip-around wallet and was wondering about how well the weave and leather would hold up against all the shuffling and shoving around that happens in the black hole that is my purse. I hadn't thought of a purse organizer but it seems like a great idea to save a potentially delicate wallet.
I'm really sorry to hear about the thread that keeps popping out. :( Since it's literally brand new, can you take it back to the boutique to see if they can either solve the problem for you or get you a replacement? With the price tag SHOULD come exceptional customer service.
BV leather is quite delicate (but I just love how soft and supple it is), I've noticed wear and tear on many of my leather goods. I feel that gives it more character in a way. Don't worry too much about it, worst comes to worst you can always just bring it back for repair.
