If you have an office at your workplace, you usually have a door that someone can knock on to get your attention, but what do visitors do if you are stuck in a cubicle? Well, they would use the Cubicaller - Cubicle Doorbell of course. Just attach the Cubicaller with the included double-sided self-adhesive velcro to the outside wall of your cube farm opening and when someone needs to speak with you, they simply press the button, the doorbell chimes (12 different sounds - 3 Volume Settings) and you can now greet them if you wish. This is top-notch smartass workplace fun at its finest.
