OneKey KeyTag- Crypto Seed Backup (2pcs with Punch Tool), Up to 24 Words Support BIP39 Cypto Wallets, Titanium Plate, Cold Storage Cryptocurrency Compatible with Ledger, Trezor, Safepal, Keepkey

This is my favorite seed backup option. Compact and inconspicuous as much as it can be. I have a couple cryptosteels plates with slide in letters. They are overpriced for what they are and feel kind of cheap. Durability of the onekey is top notch being titanium. The 2X24 word seed + 25th word is great. Get these backup plates.

From the photos I thought the tiles were single-sided & 1 had words 1-12 & the other had 13-24. However, when it arrived I was pleasantly surprised that they are double-sided so you can do 2x24 word phrases (or 2 copies of 2.)

From the encrypted method to record a seed phrase, to the tiny, inconspicuous seed plate, and even the beautiful packaging, everything is top of the line---until you go to punch the plate with the completely useless punch tool provided. No mater how much force I applied, I literally could not get the included punch to make a single hole in the plate. I had to purchase a new punch that worked. For the price, the included punch should work flawlessly. For that reason I subtracted two stars. The new punch I purchased worked with ease, required minimal force, and caused me no pain while using the tool. For those willing to accept that fact that they too may have to purchase a punch that works, I recommend this seed storage system.

It’s a very clever way to store your key phrase or any phrase password for that matter.

At first when you're reading the instructions, it may seem a bit complicated or overwhelming. But once you go back and reread it a couple times you'll start to understand the decoding process and how it all works.As far as the quality and the workmanship of the tags and punch tool, everything was very high quality. The punch tool actually has a spring mechanism inside of it to give it some shock absorption before it punches the tag hole.What's great about the whole thing is, once you have punched your tags with your coding, the punch tool itself can be used in the future for other projects and good to keep in your toolbox.Everything about this product in the company are first class. Even the boxing was very high-end like you would see with expensive video cards. It seemed a bit pricey for what you get, but maybe that's because of the titanium.

Not much to say. A simple product that does exactly what it is supposed to. Resistant to pretty much anything you might encounter...fire, water, earthquake, alien invasion, etc.

Excellent way to keep your seed secret.
