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. Review: One Seed letter card missing - After receiving this product, it was shown to be high quality; however, a few screws were stripped. I was able to get them out but cannot reuse them. The item came with four extra screws. It should have come with more. When getting ready to enter the seed, it was discovered that the four letter “cards” are numbered. I received two “1”s, one “2” and one “3”. I assume that there is a “4” that I did not get because I do not have the later letters of the alphabet. This makes entering my seed basically useless as I cannot properly record several seed words. Will try to get the “4” through the manufacturer and will update. Follow-up: Received a very prompt reply from manufacturer’s customer service who sent a unit within 2 days! Based on the quality of the product (despite the screws), I changed my review to a 5 star rating. They certainly stand by their product and have great customer services! ## Features - ★ DURABLE AND INDESTRUCTIBLE★: Made with grade 304 Steel, the Keystone Tablet Plus is the long term solution to helping you safely store and backup your wallet’s seed phrase due to its resistance to corrosion.

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 ### ⭐⭐⭐⭐⭐ Solid build, works as advertised, cannot understand the 1 star reviews *by B***O on February 14, 2021* I got my Cobo Tablet yesterday.

Absolute best solution to store your Crypto offline. *by C***Y on December 22, 2020* I purchased the Cobo Tablet Plus. I first purchased the COLDTI plates to store my seed, cheap. The only problem? That thing is freaking strong! I banged on it with a hammer a few times and realized that this was simply unpractical. Then I searched harder to a much easier device to use but would likely withstand a fire if my house burned down. I tried the Cobo Tablet Plus and it was significantly easier to use. No tools needed other than some screws. It feels really rock solid piece of metal that I have complete confidence will stand up in a fire. It also just feels really nice to hold in you hand too and has a smooth finish. You can secure it with a combo or key lock to deter quick peepers(though won't help if the tablet gets stolen). You could probably run over this thing with a car or larger and I highly doubt it would even appear to be phased. I compare it to armor on a light military vehicle. Overall I am extremely satisfied and It wasn't crazy expensive like some other ones. Simple to use and you can set it up in 10-20 minutes using the full word list. I really can't imagine this product getting much better. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/223774620-keystone-steel-crypto-cold-storage-seed-backup-compatible-with-all](https://www.desertcart.ae/products/223774620-keystone-steel-crypto-cold-storage-seed-backup-compatible-with-all) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-10-09*
