i went to the chanel boutique to pick up my black metallic 226 the other day and the sa was telling me that chanel offers free refurbishing for a year. if your bag is dirty or a little worn, just take it to them and they will make it new again. however, it's only free for a year and i'm not sure how much it could wear out in a year... i asked him if they treated the bags at all, and he said that they put a protective treatment on the bags to make them a little more durable. i don't know how accurate that information is since i was asking in reference to the black metallic. for that bag, he said that they would treat it so that it becomes a little more water resistant. i'm definitely going to take my white bag in after the summer and have them refurbish it so it'll be all ready for next spring/summer! ps. sorry if this is widely known, i have just never heard of it before.
