Before I plunk down 5K or more on a new flap bag I wanted to know if the lock on the flaps show wear and tear from opening and closing it. I was thinking of a black flap with silver hardware. I wanted to know if the silver coating wears off , tarnishes or chips. If it does show signs of wear and tear can you show me photos? I do lots of "research" before spending thousands of dollars on a handbag. Thank you so much.
