Don’t believe them
I don’t know, sadly counterfeiters have gotten so good that it is incredibly difficult to decipher. All I know is that 2 other authenticity apps said my balenciaga hoodie was fake & these guys insisted it was real. I will never know the real truth, but there were some pretty obvious discrepancies that I noticed that shouldn’t be there and they said “remember these are mass produced and sometimes the quality is not perfect”; I totally disagree!
