try to sniff the handles, if they smell rubbery then i am very sorry that you got yourself a fake Fendi. a few years back i actually bought one myself and i knew the second i received it that it was fake because of the somewhat rigid and rubbery smelling handles. even though everything else seems o..kay but i knew it was fake because a real fendi would never smell or feel like that.
i hope this helps, that was my first fendi and i was young back then, 400 bucks wasted but a lesson learned.
