Authentic Fendi Spy Bags are still available on Ebay but knowledge is the key to buying an Authentic Fendi.
If you see a yellow tag hanging from a Fendi handbag, please proceed with caution. I have reviewed two replica handbags that came with this yellow tag and I have never seen one on an Authentic Fendi.
The Zucca Jacquard lining on Authentic Fendi Spy bags will be perpendicular to the top of the bag. If the lining shows a sheen to it or if it is not properly aligned, it may be a replica. Fendi uses several different types of fabric lining on their handbags. The Zucca Jacquard Lining I have seen on Authentic Fendi Spy Bags, lines up perpendicular to the leather seam around the top of the bag. On some earlier manufacturing runs, Photo A the Top and the Bottom of the FFs are lined up to the seam. There are newer releases, Photos B, C. Notice the tops of the FFs do not meet with the seam, but they are perpendicular and even to the seam.
