Based on these pics it looks like that it was very carelessly used. Surprising if it really is a half a year old bag. The lock looks ancient.
But the canvas looks quite OK. If the canvas has no tears, cracks, and the corners are in good shape, then only a handle replacement is needed, Vuitton will replace them for €85 a piece, it does worth it I believe.
I'm wondering how the lining looks though. I fear that if the outside was treated this poorly, the inside also might be dirty and it is not super easy to clean. That is the only thing I'm really afraid of.
