You can also tell, if you look at the "K" on the word "Black", on the fake one, the K isn't completed on the upper stroke. I've also heard that the part where the liquid sprays out of, on a real one, the hole is white; on a fake one, the hole is black. I've been seeing ALLOT of fakes on eBay lately. It's a shame. I fell for it and bought a fake. They do smell similar but aren't as strong and longevity SUCKS. ☹️ I wish people would just STOP making fakes.
