I have found my ear really hurt when coming back home and the reason : the stud of the earring is rusty. It is an earring I bought for $800 from Sydney Chanel boutique . Even earrings from $2 shop use surgical or stainless materials... I can’t believe my eyes!! And my Chanel sunglasses, the words on the legs are all fading away. One becomes “chane”, another “H N L”. I went to Westfield Chanel shop complaining about it and only told to put it to service with no guarantee it will be repaired and on my own cost
