The video features a close-up of a person's hand as they paint a detailed design on their fingernail. The person uses a small brush to carefully apply black and green nail polish to create a unique pattern. The design appears to be a combination of geometric shapes and lines, with a green stripe running down the middle of the nail. The person's hand is steady as they work on the intricate details of the design, and the finished product is a striking and artistic nail art piece.
