Does what it says!

I have purchased two of these. One for the office for paperwork that should be under lock and key AND one for home to keep important documents in too. I value the Sentry Safe products - and own others. I like to have a place to safely and securely store papers. The safe is not to heavy (weight) for lifting - if needed.

The safe I purchased is the correct size, built well and at a prize I could afford. I couldn't find this item any place other than Walmart and arrived within a week

Helps protect our documents

We have a Smaller one that would not hold all the documents that we had inherited for my relative passing. They have an older safe with a key and combination. We only wanted a key type this fit the bill and since we already had a different one from Sentrysafe we Knew it would work.
