B-finish 12-word plate


These plates are leftovers from a previous batch and did not get any surface treatment to make them look nicer. Only one side is numbered (from 1 to 12) so this plate can only be used for 12 word seed phrases.

Keep your seed phrase safe from water, fire, EMP (electromagnetic pulse) and other disaster. Made from extra thick stainless steel.

All our backup plates have been awarded the highest rating (AAAA) in Jameson Lopp’s Metal Bitcoin Seed Storage Stress Tests.
