The video shows a close-up of a person's hand with long, pointed nails. The nails are painted with a glossy black polish, and the person is using a brush to apply a clear topcoat over the black polish. The brush strokes are smooth and even, covering the entire nail surface. The person's hand is steady, and the topcoat is applied carefully to ensure a smooth finish. The background is blurred, but it appears to be a light-colored surface.
