We've all seen movies, especially cartoons, in which secret rooms or safes are hidden behind picture frames. This frame is even cooler. Even if the thief looks behind your cheesy family portrait, he'll be hot, hot, hot in terms of closeness, but he won't be able to see the safe. That's because the frame is the safe!
You can stash important papers in the Picture Frame Box or hide your private naked photos or perhaps stacks of cash. You could even put in jewelery and other precious objects, but your secret would be out pretty quickly if someone rattled the frame.
Much better than those wall outlet safes. Still, I don't think anything gets sneakier than this headuce...
