A tiny little piece that goes above a peephole and is held in place with a small nail. Prevents any weirdos from looking into your condo/hotel/office/whatever. When YOU need to use the peephole, just slide it out of the way and take a peek. Release it and it'll cover the peephole again. Thanks, gravity!
-Punch a small nail through the hole into your door, with the 'cup' part over the peephole.
-Enjoy your privacy.
