This safe will be the second most important item in your life. The first most important item? In the safe!
If this safe was the most important thing you owned, would you leave it lying around? NO. You'd put it in a safe designed to hold a safe! Because an important safe that wasn't in a safe would just be stolen by some other safe lover with no respect for private property.
But this safe here, this safe WON'T be the most important thing you own. The most important thing you own will be the thing INSIDE THE SAFE. So if someone comes into your abode and looks around, they won't find the important thing, they'll find... THE SAFE!
And face it, who's gonna steal a safe? Especially when they could just buy one here today for such a low low price.
