If so, this is not even a hardware wallet in the first place! It only holds a single private key, which you can only view by peeling off the sticker.
You can easily (and much more securely) make this yourself. It's highly insecure to just use a private key that someone generated for you, as they can easily have a copy of it and sweep it immediately after funding, or later down the road.


Anyhow, for backing this thing up, you'd want to back up the private key here (which you could engrave into metal), but then the sticker is peeled and I'm not sure that you can stick it back on.

Damn, this is so misleading. They mention BIP38, which is just private key encryption. Meanwhile you want BIP39, which gives you a wallet that deterministically creates keys from a seed phrase. I'm sure that's why they put BIP38 in the advertisement, as otherwise it's not really a feature to brag about.
