12-Word Punchplate Starter Pack
Two plates. One tool. Everything you need to start securing your Bitcoin on steel.
This starter pack is the fastest way to go from paper backup to permanent backup. You get two 12-Word Punchplates and an Automatic Center Punch Tool — no separate purchases, no hunting for compatible tools. Open the box and start punching.
Two plates means you can store your seed phrase in two separate locations. A fire takes out your safe? Your second plate is somewhere else. That's the whole point of redundancy — and it's the setup most security guides recommend.
Each plate is double-sided 304 stainless steel with a precision-etched grid for your full 12-word BIP39 recovery phrase plus an 8-character label. The included punch tool delivers clean, permanent marks every time. Illustrated instructions and a permanent marker for pre-marking round out the kit.
What's Included
Two 12-word Punchplates (double-sided), one Automatic Center Punch Tool, one permanent marker, illustrated instructions, and a BIP39 word list reference.
Specs
Dimensions (per plate): 5.25" x 1.4" x 0.070" — fits in a standard safe or deposit box. Material: 304 stainless steel — resists fire, water, corrosion, and crushing. Compatibility: Works with any BIP39 wallet (Ledger, Trezor, Coldcard, and others). Capacity: Two 12-word recovery phrases + 8-character identifiers.
Who It's For
Anyone getting started with self-custody who wants a complete kit and a redundant backup from day one.
How It Works
First four letters,
punched into steel.
Each BIP-39 word is uniquely identified by its first 4 letters. Each word gets its own column. Each letter tells you which row (A–Z) to go to. Mark the quadrants clockwise: 1st letter = top, 2nd = right, 3rd = bottom, 4th = left.

Bitcoin Backup Questions, Answered
Everything you stamp into steel matters. Here are the most important things to know before backing up your Bitcoin seed phrase.
What should I put on a Punchplate? +
Only your wallet recovery words, exactly as generated by your wallet.
Do I need a 12-word or 24-word Punchplate? +
Use the format your wallet gave you. If your wallet generated 12 words, use a 12-word plate. If it generated 24, use a 24-word plate.
What about a passphrase? +
If you use a BIP39 passphrase, remember that your seed words alone are not enough. You need a separate secure plan for preserving that passphrase too.
Should I make more than one backup? +
Yes. Many Bitcoin holders keep at least two backups in separate secure locations in case of theft, fire, flood, or loss.
Can I test my backup? +
Yes. The safest approach is to verify that your recovery words can restore the wallet before moving bitcoin or relying on the backup long term.
What if I punch the wrong spot or letter? +
No stress — Punchplate was designed for this. If you hit the wrong spot, simply punch the exact same spot 3–4 times. This creates a dense cluster of dots that is impossible to confuse with a real punch.
Every valid character on the finished plate is always a single clean punch. Canceled marks stand out clearly as overlapping groups, so you (or anyone reading it later) instantly knows to ignore them and move to the next valid letter.
