In the video, a person is holding a makeup brush with a white handle and a white brush head. The person is using their thumb and index finger to twist the brush head, which appears to be made of a soft, spongy material. The brush head is being twisted back and forth, and the person is applying pressure to the brush head, causing it to compress and expand. The background is a solid light blue color, and the person's nails are painted with a clear polish.
