Beibei's products are really affordable, and there are frequent activities, but it's really helpless after sale. Fortunately, it doesn't work when encountering problems. This website puts goods from different suppliers like Taobao, and the goods of the same order are sent from different places. In fact, it's nothing, except that the website can't put pressure on suppliers, and even if you encounter after-sale problems, it won't work. As for the brand authenticity, I can only say that the cosmetics I bought are genuine, and I will check.
