The image shows a display case with four small, rectangular objects on it. The objects appear to be made of stone or a similar material and have a smooth, polished finish. They are arranged in a row, with the largest object in the center and two smaller objects on either side. The background is a dark blue color, and there is a white sign on the right side of the display case that reads "Tools" in Chinese characters. The sign is located in a museum or exhibition space.
