The image shows two small objects on a clear plastic tray. On the left side, there is a small black knob with a round base and a small knob on top. The knob appears to be made of metal and has a small hole in the center. The right side of the tray has a rectangular shape with a flat top and a flat bottom. There are two blue circles on the tray, one labeled "7" and the other labeled "8". The background is blurred, but it seems to be a beige-colored surface.
