ColdTi - Titanium Bitcoin Seed Plates for Ultra-Secure Crypto Seed Phrase Storage (2 Plates, Punch Set & Seals) - Premium Seed Phrase Metal - Alphabetic Punch Set Included

Love the concept of a recovery seed STAMPED into titanium, a metal which won't rust or corrode. And a melting point over 3000°F. Average temp of a house fire is 1100°F, with peaks between 1,200 and 1,800°F. Meaning the plate would survive a fire even if it wasn't locked in a safe. One minor complaint is the really tiny punch set included with the kit. Almost too small to read (2mm??), especially if you don't use good technique while doing it. I practiced on some scraps of metal first, decided it was a lost cause. Ended up using a 3mm (1/8”) set which was much more readable. But the etched blocks spacing would easily allow a 4mm (5/32”) or even 5mm (3/16") . (See attached picture, their 2mm on top, my own 3mm below.) Suggest purchasing only the plates, and get a larger punch kit elsewhere. Important -When you actually punch the letters, use a solid smooth metal backing plate for best results. Bench block, jewelers block, anvil, metal vice, or anything similar. Attempting to do this with a wood backing (or rubber, concrete, carpet, etc) is going to result in a warped plate and dimpled characters.

Ignore the people here that whine about this product. It’s extremely easy and effective to do this. If you have a hammer and flat cement floor it’s dummy proof. Excellent product!

I cant give this enough stars. First of all the kit works exactly as advertised. We did have a hiccup i got 2 of the same letter. When I reached out I not only got an immediate response but they same day they shipped me put the correct letter. Superb customer service and I could not be happier! If I ever need another one of these kits I wont order from anyone else. This company goes above and beyond for thier customers!

Leah package arrived busted and broken. The metal punches were all over the place in the packaging for the plates was torn open. The plates are OK, much smaller than I thought. The punches, however, our way smaller than I thought and appeared to be very cheap. There’s nothing to denote what letter they are. You have to squint your eyes and look at the punch end and try to figure out what letter it is. I can see why there are so many complaints about how long it takes to punch your cards. And this is also why people make mistakes doing it. I recommend buying a better punch set and just getting the plates if you are OK with small plates. Or find a different manufacturer altogether.

First one I received had one punch left in it, the other ones were MIA. Went through the link/customer service provided and got a replacement quickly. The plates work well but are thin. The punches aren’t super deep so you’ll get some haloing from the outer edge if you hit too hard. Be careful not to hit to punch too hard, it will imprint a bit on the back. It wasn’t readable but made a blemish and the plate will warp as you go. You just bend it back or flatten it with a hammer. Not sure how it does on other materials. Get ready for a long adventure if you’re doing a seed phrase, took a little back pain and a few beers in the garage but overall did its intended job. Recommend doing on a hard surface in the garage; don't do this on the kitchen counter.

It's a good option to store your 12- or 24-word BIP39 seed phrase. It is sure durable and I guess, it will withstand all imaginable disasters. It takes some time to punch in words in and I recommend doing it on a leveled and hard surface. Do not do it on a wooden table! It needs to be concrete or hard stone. The only downside is that on the backside you will see dents were the letters are, but it's not readable. Also, the hole plate was slightly bend after the work was done. I had to hammer it back a little to close it again. For the prize it is a very good option.

Easy to set up and very user-friendly

It was not super easy to hammer all those letters, but overall it is exactly what you need and at a really reasonable price.

Funktioniert sehr gut

Perfecto,

Pratique mais difficile de faire des frappes propre

The item was delivered damaged and the stickers were all over the place.
