Discrete

 

Most people who will see this metal card will have absolutely no idea what it is. Just a steel plate with holes? No, the holes represent the binary code of your seed words.

Indestructible

 

Virtually indestructible: the 304 Stainless Steel can withstand 1400 Degrees (2552 Fahrenheit). Slamming, crushing, folding, explosions, flooding. If you can find it, you have nothing to worry about.

Compatible

 

The card is compatible with all major wallets. It has room for 128 bits (12 words) and some additional bits. For 24 words use two cards, and keep them distinct by drilling the dedicated bit.
