I have a quesiton and would be really greatful for some help. I just took a look at my the set of keys that go with my speedy. I noticed that it seems to be changing color, it's getting darker. Has anyone had this problem before? I purchased my Louis on eluxury and took it to the store to get it looked over. Its just that for the amount of money I paid for this bag you would think they would provide a key that doesn't change color. Help
