The bottle of fake/diluted T400 has a hologram and the rest of the label looks almost identical to the good bottle I have. The size of the type is a little different, but both labels have rounded corners. The fake bottle's stopper goes further into the neck of the bottle than the good one, which you can't really even see. Finally, the good bottle has a exp. date of 12/2006 while the lame one has 12/2009.
