I am looking at a Forever Mamma Fendi bag (my first). I've been reading about Fendi bags on this forum and from what I understand each bag should have a hologram tag and a leather strip with a serial number. Are these tags located in the same spots for each bag or does it depend on the style of bag? I have only purchased LV and Bottega Veneta bags in the past. Any help from you all would be GREATLY appreciated. Thanks in advance.
