In this world, there are many sellers online who tend to give fake promotions by saying their perfumes are all original. In my case, I have done an experiment as some perfumes would have their own standard on how we test it. For example, you could see the printed brand or the packaging are up to the standard. Next, you can shake the perfume and the original perfume would not produce much bubble. You should also beware of the scent and you could still smell it after 3 hours, it is not grade AAA or the fake ones. Lastly, you should be aware of the price too. Some sellers would sell it with lower price because they have tester stocks and you can simply go to JPO to have branded perfumes with the best quality and the best price in town.
