I don't know about you guys, but I bought a LE MAC Hello Kitty eye palette from http://www.glambot.com and they were below retail value and they were super clean and new-looking when I got them, so they probably took a lot of time out to clean them. Iuno.
I perused through their site and blog and found that they also check everything for authenticity (and even write articles about how to spot fake stuff), so that put me at ease as well. Why would you dedicate time to write posts about fakes if you're going to sell fakes? Seems weird to me. Here is the
post to find fake MAC eyeshadows. The pink eyeshadow is real and the black one is fake, FYI.
