High Flexibility
The capsule features adjustable separators, offers more capacity – 123 instead of 96 characters most other solutions provide – and comes with a full ASCII-character-set supporting random passwords with numbers and symbols. All of the characters are deeply stamped into the tiles to provide maximum longevity.
This means that the capsule can securely store a random password without separators, an unabbreviated 12-word mnemonic seed, or the first four letters of a mnemonic seed made up of 25 word phrases.
