Key Features to Look For
- Fire Rating: When I was shopping around, I discovered that fireproof boxes come with different fire ratings.

Material Matters
I learned that the materials used in fireproof boxes vary. Steel and reinforced plastic are common, and each has its benefits. Steel offers durability and a higher fire rating, while plastic can be lighter and easier to carry. I ultimately chose a box made of steel for its superior protection.
Budget Considerations
Before making my final decision, I set a budget. Fireproof boxes come in a range of prices, from affordable to high-end. I found that investing a little more often means better protection and features. I was willing to spend a bit more for a box that provided peace of mind.

I also visited local office supply stores to see the boxes in person, which gave me a better feel for the size and build quality.
After going through this process, I felt confident in my choice of a fireproof box for legal size documents. It’s not just about storage; it’s about protecting what matters most.
