Fendi handbags have specific features that make it possible to quickly identify a fake. The fabric used in constructing the bag, the stitching and the authenticity tags located inside the bag are all important to check when identifying an authentic Fendi spy bag.
As of 2014, Fendi bags are sold with a hologram sticker located in the bag's interior pocket. The hologram sticker is one of the most important things to look for when authenticating a handbag. The quality of the materials is also very important. A fake Fendi spy bag may be made of cheap material, or the "F" logo on the bag may not line up properly. Additionally, Fendi uses YKK zippers, and the stitching on the bag should be perfect. Any flaws, missing hologram stickers or rough, imperfect material may indicate a fake Fendi spy bag.
