In the video, a person is holding a black and white computer mouse. The person presses a button on the mouse, and a blue light appears on the bottom of the mouse. The person then presses the button again, and the light turns off. The mouse appears to be a wireless model with a scroll wheel and two buttons. The person's hand is visible, but their face is not shown in the video. The background is blurred, but it seems to be an indoor setting.
