3D-Printed Washer Jig & Letter Stamps
Product detailed description
Protect your Bitcoin seed phrase with a virtually indestructible metal recovery wallet. Your seed phrase is permanently recorded by punching it into M8 steel washers, which are then secured on a bolt with a nut.

Unlike other sellers, this kit already includes a 27-letter punch set that is compatible with the 3D-printed washer jig.
Please note that the M8 washers, nut, and bolt are not included, but they're readily available and inexpensive at any local hardware store.

- Label the washers with letters at the top (A=1st, B=2nd, etc.) to indicate the word order. See sample ("B CRYPTO" meaning the 2nd word is "crypto") in the item images.
- Secure the washer in the jig with tape from the bottom to prevent rotation during stamping. The tape is not included.
- Position the insert in the jig, select the letter, insert the stamp, and strike firmly with your hammer.
- Rotate the insert in the jig and stamp the next letter.
- Remember to purchase a few extra washers for practice and corrections.

- Always use a passphrase with your seed phrase. Strong passphrase protection may significantly delay unauthorized access.
- To make more copies of your cold wallet, simply get extra washers, nuts, and bolts, and reuse your punches with the 3D-printed jig.
