Review: Heavy and Substantial Box - Was looking for an alternative to a safe that would be fireproof, so we could keep a few important documents in, for my mother. At first we ordered a safe, but it was supposed to be fireproof yet had tow large inch wide holes in the back. Send it back and instead ordered this - and its perfect. This item is heavy and robust, It seems to be double walled and substantial. You can fit documents, and a few small items - just right for the purpose we needed and it comes with two keys. Its a goods solid quality and I would recommend.
Review: Strong, sturdy and very robust. - I was so surprised at how heavy this item is and how robust it is. Nice strong case. Locks lovely and two keys nice size bit smaller than a brief case.

## Questions & Answers

**Q: If buried, how safe are the contents from the elements?**
A: Just by looking at mine, If it is locked and undamaged and used for the storage of documents and digital media . probably safe for a short time against accidental buria in damp rather than waterlogged soil.  But there is no way it is designed for deliberate lnng-term burial

**Q: My safe will not open - does anyone know what to do?**
A: This happened to me I had to pay to get a locksmith to open it for me. These are from a bad batch I believe, I bought another same company everything, different type of closure tho and never had a problem since, that was 3 years ago and my new one still works fine. Hope that helps

**Q: Is there a requirement to open the box for 30 minutes weekly to avoid moisture build up?**
A: I have used this type of Safe for some years & have noticed no condensation moisture problems. However we do store it in a warm environment and I would not recommend keeping it in a very cold or damp environment. I hope this helps.

**Q: Plastic casing shows a split externally after storage- faulty but no obvious guarantee**
A: The casing is not split in this product which I have.
