Most product pages tell you what a kit will do for you. This one is going to tell you what is physically in the box, because a backup is not a marketing promise, it is a set of objects that either work in ten years or do not.
The plate
One solid piece of 2 mm commercial grade titanium, cut as a single unit with polished edges. Not two plates riveted together, not a frame with an insert. One piece.
The face has laser-engraved numbered cells, so the order of your words cannot be scrambled by a smudge, plus two sidelines for a note. Four quarter-inch utility holes sit in the corners. The back is blank on purpose, so you can put a warning or an instruction there without touching the words.
Two sizes. The 12 word plate is 1 7/8 inches wide by 3 inches tall. The 24 word plate is 3 inches by 3 inches. Both are rated to 3,000 degrees Fahrenheit, 1,650 Celsius, non-corrosive, and crushproof.
The guide
This is the part that decides whether your first attempt looks like a backup or like a mistake. The patented stamping guide holds the plate square and holds the stamp aligned over the cell, so the letters land in the right place at the right depth without you needing a steady hand or any practice at all.
There is also an adapter in the box, which exists for one reason: the 12 word plate is smaller than the 24 word plate, and the guide still has to hold it securely. That adapter is the kind of detail you only think about after you have already tried to do it the hard way.
The stamps
A full uppercase A to Z set, with side markings and indicator lines so you can tell which way the letter is facing without squinting at a curved piece of steel. The Deluxe Kit adds a full number set, which matters if you want to stamp numbered lines or keep a written index alongside the plate.
One honest note that the manufacturer makes themselves: the letter and number stamps in the Seed Stamping Kit are a different font from the stamps in their ClearCode sets. If you are stamping a passphrase or a private key with mixed character sets, do not mix the two kits on the same plate, because some characters become difficult to tell apart later. That is a real limitation, stated up front, and it is the sort of thing you want to know before you strike metal rather than after.
The hammer and the anvil
The Deluxe Kit ships a 2 lb metal stamping hammer with a brass tip. Brass absorbs the shock of the strike instead of transmitting it into your wrist, which is the difference between ten minutes of work and ten minutes of regret. The steel anvil underneath gives you a solid base so the impression goes deep instead of bouncing.
Jameson Lopp, who has broken more hardware than most people have owned, called the kit robust after testing it. Rex Kneisley of The CryptoDad, who has handled a lot of stamping tools, said the brass tip absorbs the strike shock better than steel. Those are the two details that actually matter when you are holding a hammer.
The test strip
A titanium strip cut from the same metal and thickness as your plate, included so you can practise before you commit. This is not a gimmick. Your recovery phrase is the one thing in your life where you want the first attempt to not be the attempt.
Strike a few letters on the strip. Feel how hard you have to hit. Then do the real plate, once, correctly.
Basic or Deluxe
The Basic Kit is the plate, the guide, the A to Z stamps, the test strip, the adapter, the instructions, and the foam-moulded storage box. It is for people who already own a suitable hammer, anvil, and number stamps.
The Deluxe Kit is everything above plus the number stamps, the 2 lb brass-tipped hammer, and the steel anvil. If you do not already own a stamping hammer, this is the version that lets you finish the job the day it arrives.
What it is not
It is not a hardware wallet. It does not hold coins, it does not connect to anything, and it has no firmware to update. It is the backup for the thing that holds the coins, and it is deliberately the least interesting object in your setup.
That is the appeal. Nothing on it can fail, because nothing on it moves. Read the fire and water case for metal if you want the failure modes in detail, and the node plus hardware wallet setup if you are building the rest of the stack.
Black Friday: the Titanium Seed Stamping Kit is $127.60, down from $220.00, while the sale runs. Both the 12 word and 24 word plates are available in Basic and Deluxe.
