I can't really say, I did buy a few times from a person from Hong Kong and every item I've bought was an authentic one, but I'm still trying to avoid sellers from Asian countries.
The items look good, so the feedback, I think she/he is a re-seller. The Blue Bolide she or he(whoever that it) is selling is a Web II and not a Bolide.
I think he's authentic, and he may be listed on www.mypoupette.com as an authorized seller. That said, I would NEVER buy from anyone outside of the US., Canada or the U.K. You will not qualify for Paypal Buyer Protection. Call Paypal directly for more information.
