It is always fun to have a hidden compartment. This mirror sets out from the wall with the shelves behind it. If it is hung on a wall at the end of a hallway, most people will never even notice the second shelf hidden behind the mirror. If wallets or keys are typically kept in the entranceway for convenience, hang this mirror on the wall and put those items on the hidden shelf so they are still accessible but not visibly out in the open.
Keep certain items out of direct eyesight by placing behind the second hidden shelf.
In the kitchen, keep medicines on the hidden shelf out of the direct reach and eyesight of children.
A second hidden shelf is behind the mirror and is 19.75"L x 4.5"W
20.5"L x 4.75"W x 30"H
