Private keys are pre generated by the manufacturer. Very crazy IMO. I think it is a shitful wallet. OP shouldn't have rush to buy it, before he reads what is it all about...
You will receive a wallet with a pre generated private key, trusting that the manufacturer don't have them.

Thanks. I missed that discussion.
Would be great if OP (which I'm not sure if it's related to the "Ballet" wallet) could answer some of these user's concerns - mainly stuff like this[1]. But this does look like just a cool "paper" wallet generated and made by a third-party. And considering that the cheapest one costs $35, I don't really see the advantages of using that over an true hardware wallet or just a real paper wallet.
