...Good evening everyone! I would like to buy a used perfume, a "Wonderoud" (Comme des Garcons) but I have noticed that there is no batch number on the flacon. The seller told me that it's not fake, and showed me other flacons of the same brand (different perfumes) that had batch codes printed on the bottles, but I would like to know if this kind of perfume has no batch code indeed. If there is not, I would get that it's a fake. Thank you for your insights!
