Only The Original Cryptosteel Cassette is 100% timeproof
The Cryptosteel Cassette is the product that started it all and established the market for offline metal wallets.
The Cassette is a pocket-sized stainless steel unit designed to securely store the alphanumeric data of your choosing with no need for specialised 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 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.

Standardised Tiles vs. Hand-Written Solutions
Our aim is to standardise the offline information protection system and provide a solution right out of the box. You don’t need to think or worry about buying additional materials or special tools. You don’t have to learn the hard way how painful engraving metal can be – no specific knowledge or safety equipment is needed. Simply open the pack and get started – everything you need is right there.
We use a classic, easy to read font that will be legible 10 or 1000 years from now. Hand engravings will naturally differ from person to person. Over time, you (or your heirs) may not be able to retrieve the information from a hand-written backup due to style, ambiguity, or decay. Using standardised tiles, you can change, undo, or redo the data you wish to be guarded. Should you make any errors, you can easily correct them.
FAQ
Choosing the Cryptosteel Cassette offers several key advantages over other manufacturers. The Cryptosteel Cassette is made entirely from high-quality stainless steel, including all parts such as screws and rivets, ensuring superior durability and protection against fire, water, and corrosion. Unlike many alternatives, the Cassette’s letters are not laser engraved but deeply stamped, making them permanent and resistant to wear over time.
Furthermore, the Cryptosteel Cassette was the first original solution for offline seed storage ever developed on the market and has since been copied by many other producers. This pioneering design set the standard for secure, offline seed storage, conforming to industry protocols like BIP39, ensuring compatibility with most cryptocurrency wallets.
By choosing Cryptosteel, you are investing in a product that offers maximum protection, long-term durability, and a proven track record in safeguarding your digital assets.
Cryptosteel Cassette: Designed specifically for seed words, with 24 slots, each slot holding 4 tiles. The entire seed phrase is visible upon opening the cassette, providing a straightforward way to safeguard your seed phrases. It includes only uppercase letters.
Cryptosteel Capsule: Holds up to 123 characters, offering flexibility to store any password, seed phrase, private key, or other secret. The letters are stacked on a core, making them unreadable at a glance, ensuring higher security. The set provides all ASCII characters, including upper and lower case letters.
Both provide robust protection against fire, water, and physical damage. Choose based on your data storage needs and preferences.
You do not need any special tools to assemble the Cryptosteel Cassette. The process is straightforward and can be done manually. After placing your character tiles into the slots, close the gate and engage the latch by pressing it down. Finally, use one of the letter tiles to tighten the screw by turning it clockwise. This locks the gate and latch in place, ensuring that everything is securely fastened. The entire process requires no additional tools, and your sensitive information is securely stored.
The Cryptosteel Cassette can hold up to 96 characters. This capacity allows it to store a 12, 18, or 24-word seed phrase by using the first four letters of each word, which is sufficient for BIP39 standard recovery phrases. Each of the 24 slots in the Cassette can hold up to four tiles, making it ideal for securely storing your mnemonic seed phrase.
