Hi, thanks all for the sweet comment!!
The birthday card was mail to me and I received it from my letter box. I guess it's a customer service thing. They will send you birthday card during birthday month. Same for Louis Vuitton in my country.
I do think the #18 caviar looks fine even thou not as rich and soft compared to the older series one. The feel of the bag really stiff and structured. I believe the shape could hold up really well. The chain leather is stiff too and result in noise as discussed in one of the thread too. My SA said this sound would really goes off with frequent use.
Hope my description and encounter be able to help those who wanted to get a caviar classic and get turn off by the recent caviar quality. It is really not that bad afterall.
