So, is this like an metal plated paper wallet? Honestly, it isn't very clear on your website. I suggest that you put a clear step-by-step on how your product works in the first page.
Something like:
1. You buy the wallet.
2. You do X.
3. Your coins are stored in Y.
4. Then you can spend by doing Z.
Everything isn't very user friendly at the moment (IMO).
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.
Take a look here, there was already some discussion in the forum about it.
