I received my black east/west stam in the mail about a week ago from the NAP sale - and it's GORGEOUS! However, I was disappointed to see, when I took the plastic off the front zippers, that one of the zippers has a nick in it. It actually looks like the gold coating chipped off in one spot. I emailed NAP and they generously offered me another 10% off (which would be almost $80, I think). However, I'm worried about this nick/chip - do you think it will tarnish/rust, and will it make it more likely that the entire zipper pull will have all its coating chip off/tarnish/rust? And is there anything I can do to repair it? I have an MJ store nearby so I could bring it by there if you think it would help. I've attached photos of the damage below - it's small, but you can see it on the center of the edge of the right side of the zipper. Thanks!
