Double plates


Keep your seed phrase safe from water, fire and disaster. Made from extra thick stainless steel and with an easy to use screw closure.
Both our Single Plate and Double Plates have been awarded the highest rating (AAAA) in Jameson Lopp’s Metal Bitcoin Seed Storage Stress Test.

All-metal tamper-evident security seal included, making it impossible to reveal the seed phrase without breaking the security seal.

The newest iteration now has two improvements over the previous version:

  • An extra hole that can be used to attach the plates with a screw or a padlock.
  • Completely flat back to make engraving or letter stamping easier.

This set includes:

  • Set of double plates.
  • Tamper-evident seal with screw.

How to engrave your seed phrase in 10 minutes.

B-finish: these are mix and match leftovers from previous batches or prototypes. They are the same quality but do not look as good as regular plates.
