I would recommend the Cryptosteel if you have a large cryptocurrency holding as it offers more security compared to writing down your mnemonic sentence on a piece of paper.

This product is awesome! It doesn’t require any outside power. It can withstand the elements . You can zap it with a million volts and it will survive.

This is amazing. Moreover, I like the idea of an open source hardware project.

Best way to stash your passwords or private keys. Love the packaging, too.
