In the video, a person is seen painting their nails with a red nail polish. The person starts by applying the polish to their thumb and then moves on to their index finger. They use a brush to apply the polish carefully, making sure to cover all areas of the nail. The person's nails are already painted with a base coat, and they are adding a layer of red polish on top. The red polish is bright and glossy, and the person applies it with precision, ensuring that the polish is evenly distributed. The background is a blue fabric, which contrasts with the red polish, making the color stand out even more.
