LV said they advise all customers when they buy Vernis now and there is instructions provided on how to maintain it. But when I bought it in Paris, the LV shop there never said anything about it. I have spoken to their customer service a couple of times and they will get back to me in a couple of days. I will keep you all posted on the progress (if you are interested).
I agree I think the darker vernis colours are a safer bet and lighter ones are higher maintenance. I have a red vernis cles which is new and there have been no problems so far. Your poor bag...you must be so upset.I have several bronze vernis pieces, and I think the darler colors show less color transfer. I don't really baby my bags, and yet, I've never seen any problems with my vernis pieces.
The lighter colors are beautiful, and I've considered them, but I will be hesitant now.
It's too bad really.
I'd be interested to hear about care options when you find out challenger. Thanks!
