No, and the prob is that they look quite genuine to me, and I usually tell the fakes apart quickly.
Just buy with paypal, wait for feedback, if they are fakes you'll get your money back...
The brush sets I looked at are definitely fake (for several reasons). No two ways about it. Do not buy from this seller.
Please also remember that buying with PayPal is absolutely no guarantee you will get your money back if the items are fake.
First of all, PayPal requires you to prove the items are fake (and that may mean getting a written report from the company that owns the brand being copied) and if the seller has already cleared their account of funds then you may not get anything anyway.
