In the video, a person is seen holding a small glass jar with a black lid. The person unscrews the lid and uses a brush to dip into the black substance inside the jar. The person then proceeds to apply the substance onto their nails. The substance appears to be a type of nail polish or nail treatment. The person's nails are painted white, and the black substance contrasts with the white color. The jar is held in one hand while the other hand uses the brush to apply the substance. The background is blurred, but it appears to be a white surface.
