The image shows a display case with four different types of rocks on it. The rocks are arranged in a row and are of different sizes and shapes. On the left side of the display case, there is a small rock with a rough texture and a pointed tip. Next to it, there are two smaller rocks, one of which appears to be a stone scraper tool and the other is a smaller one. All the rocks have Chinese text written on them, which likely provides information about the tools. The background is a beige-colored surface.
