Mine is the large sperone. I love the bag. Its was 3 months old... when I noticed the peeling on the corners... just like your experience. I posted about this in the Forum. Took the Bag to the boutique... SA told me that has to be sent to repairs. 4 weeks later... They told me that it was normal wear and tear. How can LV sell a backpack... that Will peel when you used it as it supposed to be used? On your back... I took Pictures and enlarged it...to show the mánager that there was not dirty or marks.... she stayed with the pictures and stayed with the bag...again.. to work with repairs..again. really don"t know what to think... very dissapointed with the process....
