Longchamp Le Pliage Backpack

Very well loved backpack. I believe that it is authentic but don’t know for sure as I bought it second hand. It had a code (in photos) but it’s mostly illegible now. This backpack has a lot of wear. It was in fact my beach bag. Stains, tears, bubbling, the zipper works fine but has warping. See photos. Great little bag and looks okay from afar.
