This is pure trash. The mystery pack is a scam. The underwear included cannot be bought on the websites, for a good reason, because it is trash. The quality is terrible and it looks like something that a child designed. It took 60 days to deliver instead of the promised 7. And I had to pay $30 local duty fees because he conveniently forgot to mention that they weren't prepaid.
Also, you cannot send anything back. So your money is gone forever and you will be stuck with poor quality and trash-looking items.
