Is it possible for a designer scent NOT to have a batch number on the box and the bottle (or just on the box)? Today I saw bottles of YSL Body Kouros and YSL Live Jazz not having a batch number on the box. The seller said that they wer old stock. He didn't allow me to open the box to check the bottle or if the batch number was inside (like Canali Black Diamond). Hence, I canceled my purchase.
I also found Tea Rose by Perfumer's Workshop 1oz and 4oz bottles that have batch numbers on the box, but not on the bottle.
Are they legit?
