Yes, this one has been authenticated! The same was being sold on TRR for $345

Fendi has a very low resale value in my country, especially for older "unpopular" bag models. Bangkok has a huge luxury community and people tend to let go of their items for "cheap" in trying to buy new things all the time -- even Chanel; the prices are way better here on the resale market. We have a very cyclical, impulsive fashion culture over here where a lot of older bags are pretty much deemed to be of barely any value so people will sell to resellers in bulk just to get rid of them. But of course, it depends on who is looking at the bag. I personally really like it so it was a deal for me.
