In the video, a person is seen holding a nail polish brush and applying it to a long, fake nail. The brush is being used to apply a clear coat of polish to the nail, which is already painted with a pinkish color. The person is carefully applying the polish, making sure to cover the entire nail. The background is blurred, but it appears to be a room with a table and other nail polish bottles. The focus of the video is on the application of the polish and the precision of the person's movements.
