Review: Does what it says on the tin ( 316 steel ) 🤣 - High quality craftsmanship, easy to use if you do your research into these type of wallets & people the clasp is not broken it can go back in lol! When you go to close the clasp, lock it off with the wallet screw then.... stand it on its side on your desk, put a soft cloth over the popped out spring and press down on it gently but firmly with a flat headed screw driver until it pops in and you are in!

## Questions & Answers

**Q: How is this usable if ledger passwords are up to 7 words? I believe you only use 4 letters per word with the Billfodl wallet?**
A: It provides 24 words and thereoff you only need to know the first 4 letters. The total list size of words that can are used within the list are 2048. The first four letters are the only relevant ones that you need to remember as it populates the rest from what is remaining and it therefore will be a unique word for the 2048.

**Q: Hi, how does this support 24 seed words, i understand that you use 4 letters from each word but there are only 12 space in it and i need 24**
A: There's space for 24 words. 12 on each side, it's in the pictures, I also own one myself.

**Q: does this product create a risk also, in that if someone finds and steals it they can instantly access your secret keys? Or can only owner open?**
A: Yes unless you use a padlock, which will grant you a small barrier of extra protection (obviously a padlock can be removed)

If this was your only backup and it was stolen, you'd be screwed.
