Before you start
A few things to know.
Will it work with my wallet?
The cards have space for up to 24 recovery words and support the English BIP39 word list used by many hardware and software wallets. Check your wallet’s recovery format before you start.
Do I need engraving experience?
No specialist experience is required, but engraving takes patience. The stencils help you form each letter. Watch the guide, use a stable surface, and take breaks when needed.
How long should I allow?
Allow around 30 minutes per card as a starting point. Your pace and phrase length will affect the time. Accuracy matters more than speed, so check every word and its position.
Where should I keep the finished cards?
Keep them somewhere private and secure. Anyone who can read your recovery phrase may be able to access your wallet. Storing backups in separate secure locations can reduce the risk of losing both in one event.
Before you engrave
The engraving pen has a sharp tip. Read the instructions carefully, use a stable work surface, and keep the kit away from children.

- ❰STAINLESS STEEL BACKUP❱ Made from 304 grade stainless steel, Crypto Seed Bank® stores the recovery words you engrave into its surface. In our demonstrated blowtorch test, the card was heated until red hot and the engraved words remained readable. The comparison shows the result of that test; it is not a temperature rating or a guarantee for every fire.
- ❰CLEAR LETTERING❱ We’ve made it easier for all Hodlers to legibly engrave their crypto seed phrases by introducing a design which features integrated letter stencils. Etching your 12, 18, or 24-word seed phrase onto each of the crypto steel metal plates with the help of letter stencils is much easier than engraving freehand.
- ❰ENGRAVING PEN INCLUDED❱ Use the included tungsten tipped pen to trace the integrated letter stencils and engrave your recovery words directly into the steel.
- ❰SLIM DESIGN❱ at just 0.02 Inches (0.5 mm) thick, CSB wallet size is one of the thinnest options for seed storage on the market. Our design makes it easy to hide and store your seed words. (CSB plus size is 0.027 inches (0.7 mm) thick).
- ❰MONEY-BACK GUARANTEE❱ If you have a poor engraving experience, or are not satisfied with your Crypto Seed Bank, you’re entitled to receive a 100% refund. Contact contact@robinsandcoleman.com with your order number. Do not send back cards you have started engraving. Only unopened products should be returned, and only after we authorize the return. Never send us your recovery words or photos showing them.
