I'm so disappointed and sad that my PS11 is falling apart. Today I just noticed that there's a bald patch on the back of the flap. On top of that, the thing on the side of the flap is starting to peel off it's because that every time I use the strap, it squeezes the flap and this happens only one side. Can anyone suggest some ideas to me? I don't what to do at this point... I got this bag last December online at Lane Crawford.
