## 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.
