The Air Vent Secret Compartment is supposed to be a hidden place where you can hide your stuff. You can hide stuff under your mattress or behind various other things that a thief would want to steal, but that’s pretty unorganized. What if you could hide your valuables inside of something that’s so common, that it’s completely out of sight? With approximately one trillion air vents in the U.S. alone, the chances of a thief discovering your air vent safe are extremely minimal ( of course if he doesn’t already ready Freshome and saw this post ). To install it, just cut out a section of drywall, and put in the compartment fastening it with screws. It opens with a mechanism that is hidden in the grill and no one will see your stuff thanks to a black divider. Is not to safe, but is very well hidden you have to admit. Price : $260
