Hi Everyone, I decided to buy 2 classic flap. One is jumbo black caviar ghw and the other one is medium black caviar shw. I live 2 hours plane ride from the boutique, so I just do phone ordering. Before these purchases, I only have one classic flap, the so black jumbo. The chain hardware of my so black was thick and heavy. I was so surprised when I feel my caviars, both the chain hardware feels kinda plasticky, and they make squeaky sounds. It is as if the chains are made of plastic, and painted in gold or silver. If I did not buy it from the boutique, I will think they are fakes. The jumbo squeaky sounds is so loud and awful. Does anyone experience this? Does the sound will be better over time? I love both of the bags though, and as my babies, I will accept them just the way they are. Here is my Chanel bag family. From left to right: Jumbo caviar GHW, Medium caviar SHW, Easy Caviar Cobalt SHW, CC Crave Beige RHW and So Black Jumbo Lambskin. Thanks every one for letting me share.
