Don’t be fooled by the fact that this doorbell prop requires batteries. Once the batteries are in there, they activate the black magic our witches brewed up in the back. The eyeball stays closed when it’s not in use, but as soon as the button is pressed and the tone rings, it opens up and greets the guest with a spooky introduction to your home. It’s perfect for those people who live in the last, creepy house on the street, or if you just want to have a fun prop for your Halloween party. Measures approx. 7″ high, 4.5 wide, 3″ thick. Mounting hole on back, Eye opens and lights, makes eerie sounds when button is pressed. Requires 3 AAA batteries (demo batteries included)
