It is unbelievable that someone even has the idea to sell such things and advertise them in any connection with hardware wallets, but if someone really buys that paper wallet and thinks they've bought HW, then they're really in trouble like the OP. I can still understand that someone buys such a product because they think it has some kind of collector's value, but everything else outside of that seems wrong to me. If I wanted to give some coins to someone in such a form, then I would do it personally in a correct and safe way, and I would be sure that no one else saw that private key.
