Product description

Fireproof and extremely durable, the Seed12 Metal Backup is lab-tested and precisely crafted in Europe from premium stainless steel, withstands temperatures up to 1400°C / 2500°F, is hermetic and crush-resistant, and offers tamper-proof protection with PSW-97 Security Seals featuring a breaking strength of over 40 kg, securing your secret even against extreme disasters.
Easy to use, toolless, and intuitive, the Seed12 Metal Backup is ready to use straight out of the box. Pre-engraved letter tiles allow you to easily assemble your passphrase and secure it onto the stainless steel core. Standardized characters ensure legibility even after decades or centuries. All you need to create this metal backup is your passphrase, a quiet place, and a bit of time to arrange and verify the character sequence. High-quality, precisely crafted, and durable components provide confidence that your secret is securely protected, delivering an excellent user experience.
Universal and flexible Seed12 Security Kit is a comprehensive set designed to secure any password of up to 64 Latin letters. It allows you to record a 12-word seed phrase and is compatible with all BIP39-based hardware and software wallets. If you want to store information that also includes numbers and special characters, you can expand the kit with additional modules of the Seed Metal Backup System to secure a private key, master password for a password manager, geographic coordinates, a safe combination, or any other sensitive information.
Correctable, erasable, and reusable. This means that if you make a mistake while recording your passphrase in the Seed12 Metal Backup, you can easily fix the error by simply rearranging the letter tiles. When you change your password, for example by moving funds to another wallet, you can easily destroy the old backup and use the same kit to create a new one—without any tools, force, or special measures. It’s as simple as stringing beads on a cord.
The Seed12 Metal Backup System is modular, meaning you can gradually expand your backup setup as your needs and assets grow by adding additional modules or complementing it with products from the Seed24 line. All functional components, such as character tiles, separators, and cotter pins, are compatible across products and also fit the older version of the Cryptosteel capsule.
