In the video, a person is painting a candy corn design on their fingernail. The design consists of three horizontal stripes in the colors of white, orange, and yellow. The person uses a thin brush to carefully apply the paint, starting with the white stripe at the top, followed by the orange stripe in the middle, and finally the yellow stripe at the bottom. The person's hand is steady, and the brush strokes are precise, resulting in a clean and even design. The video is shot in close-up, focusing on the fingernail and the brush, with the background blurred out.
