## Questions & Answers

**Q: it looks like each word can only be four letters/tiles long???? what if your words are longer?**
A: Unlike some of the reviewers that don't understand how seed phrases work, the seed phrase protocol ensures that the first four letters of any word in the library is unique. So for example, if a word in your seed phrase is "short", there will never be any word in the library that begins with those same four letters , "S-H-O-R".  So, "shore", or any other word beginning with those four letters would not exist in the library. 

If you've ever tried recovering a wallet using a seed phrase, you'll find that you'll usually choose each of the 24 words in order from a list of choices, making it so you don't even have to remember what the abbreviations mean, simply match them up when stepping through the recovery process. 

Whatever you do, DO NOT do what some of the reviewers have done and arbitrarily create your own abbreviations. ONLY use the first four letters.

**Q: Another person asked if letters were etched. answer sidestepped that the tiles are also ss. are the letters etched? paint won’t survive fire.**
A: The letters are etched on the metal tiles that are crafted from 304-grade stainless steel. Since this has a fireproof threshold ranging from 2550 to 2650 degrees Fahrenheit, your recovery seeds will be safe within.

**Q: How many seed phrases does it store?**
A: It can store 24 words. Thanks for asking!

**Q: What is the diameter of the hole in millimeters?**
A: The diameter of the hole is 6 mm.

## Customer Reviews

### ⭐⭐⭐⭐⭐ This is the BEST way to store your passphrase, hands down. Sturdy, simple, it is PERFECT.
*by M***L on July 9, 2022*

If you read the reviews here, pretty much the only negative ones are from people that simply don’t understand that they only need the first four letters in their passphrase. Let me repeat that; you only need the first four letters in every word in your passphrase.Once a person realizes that, this product is incredible. It won’t burn. It can’t be ripped. It probably weighs over a pound in your hand, but it’s about the size of 5 credit cards. The only security you need, after putting your personal passphrase letters into the Keystone, is to make sure no one besides you, or your trusted loved ones, can ever find it. Tape it under a shelf or drawer. Stash it in a hidden safe or safe deposit box. With this, your crypto is safe even in you lose or break your cold storage wallet. And that kind of security is priceless.You enter your own passphrase by opening the Keystone, which has four metal plates; a top and bottom plate for your first 12 words, and a top and bottom plate for the second 12 words. You unscrew the top plate with an included screwdriver, slide it out of the way and then you put your own laser etched letters into each word spot. Then you slide the top plate back into place (you can gently lift it a little bit, if it is impacting the letters as you put it back in place), screw the top plate back in, and voila. It has plenty of letters, I wasn’t even close to running out of anything.I had the entire thing setup and stashed within 15 minutes of opening the package. Highly recommend.

### ⭐⭐⭐⭐⭐ Excellent Quality.
*by A***R on May 10, 2023*

This is a great product and very high quality.The only problem I have with it is the little screwdriver that comes with it is not a correct fit for the little screws. You have to push the screwdriver head hard into the screw to get it to grip properly. It worked out fine for me as I’m handy with things like that. But for anyone that’s not handy I could see this been difficult to do.But all in all I’m very pleased, as I said excellent quality and if you take a little care with the screws you’ll be fine. There is absolutely no need to pay $100 upwards for other wallets like this. This is as good of quality you can buy at a very very reasonable price.To the seller: you should upgrade the screwdriver to a perfect fit for the little screws, apart from that this product is 100%. Thank you 👍🏽

### ⭐⭐⭐⭐⭐ Solid build, works as advertised, cannot understand the 1 star reviews
*by B***O on February 14, 2021*

I got my Cobo Tablet yesterday. Very solid build (you could probably kill someone with it) and I had no problems with the screws. The screw driver that comes with it works, but get yourself a set of magnetized screwdrivers as it makes the process so much easier. From start to finish, it took me about 45 minutes.A quick couple of suggestions for installing the letters. 1.) Keep the adhesive layer on the letters as you go. Some will get loose and you don't want to lose them. 2.) Only remove the screws from one side at a time. 3.) Double, triple, quadruple check your words as you go along. The tiles can be hard to remove once they are in their slots. 4.) Watch which letters you use as blanks. Scan over your words and find the least used letters.Now, to all the one-star reviews saying there are only 4 letters per word and that the manufacturer does not indicate that: You probably should not be in cryptocurrency. You only need 4 letters to make the word, per the standard. That is the first 4 letters, not random abbreviations.As to the stripping of screws: Yes, the screws are small. However, most sets of screwdrivers come with the proper size for this. It's a common jeweler's screw size.Finally, I saw one review talking about removing the upper right screw that holds the entire set of plates together. You do not need to remove that. You just slide the one side out of the way, unscrew the side you are working one, close that side up, put all the screws back in and repeat.
