In the video, a person is seen washing a makeup brush under a running faucet. The brush is black and appears to be a standard size for applying makeup. The person uses their fingers to scrub the bristles of the brush, ensuring that all the makeup is removed. The sink is white, and there is a pink bowl visible in the bottom right corner of the frame. The water from the faucet is clear and flows steadily, and the person's hands are visible as they hold the brush and scrub it.
