In the video, a person is seen painting a design on a fingernail. The nail is already painted white and has a pink design on it. The person uses a thin brush to add black lines to the pink design, creating a geometric pattern. The person's hand is steady as they carefully add each line to the design. The video is shot in close-up, focusing on the nail and the brush. The person's other hand is visible in the background, holding the nail steady. The video is shot in natural light, and the colors are vibrant and clear.
