I think most of the seasonal caviars are just stamped PU leather (bonded) as they are all plasticky. I know they reinforced the boy bag corners w/ PU leather, I am sure b/c of the issues with wear there. I am sure the CCH corners as well as those were a mess. I don't doubt they are trying to use cheaper materials to make these things wear longer/ better than actually just using higher end materials (thick, dyed, top leathers) in the first place, but now even the chemical Frankenstein combo isn't working.
