The Cryptosteel Cassette Duo set is the ideal solution for boosting security by doubling your offline cold storage backup devices.

The Cryptosteel Cassette started it all and established the offline metal wallets market.

The set consists of two pocket-sized stainless steel units designed to securely store the alphanumeric data of your choosing with no need for specialized tools or third-party involvement. Each device comes with its own kit of stainless steel tiles engraved on each side.

Codes and passwords are assembled manually from the supplied part-random set of characters. You can store up to 96 characters (24 words ) worth of confidential information quickly, guaranteeing the safety and privacy of your data.

Once a desired sequence is locked into your Cassette, it essentially gains the status of offline permanence, featuring resistance to physical damage, including fire, flooding, corrosive conditions, electric shock and impact from accidents.

Optimised for Recovery Seed Phrases

Your 12-24 recovery seed phrase is based on Bitcoin Improvement Proposal 39, known as BIP39, which allows the use of a language-based mnemonic phrase to serve as your backup in the event your wallet gets lost or becomes unusable.

The words are selected from a specific list of 2,048 common English words. While not all of the words have exactly four letters, each was selected in such a way that the first four characters unambiguously identify each word. This goes for the occasional three-letter word, too, in which the fourth character is blank. So if you have four tiles, you have your word.

Cryptosteel Mnemonic can hold up to 96 characters, which is exactly what you need to store a 24-word list in the BIP39 protocol. Each Mnemonic tile kit contains an optimised character count and spread for maximum functionality and ease of use. The kits are part-randomised for an extra layer of security.
