The image shows a white display board with six different types of metal objects displayed on it. The objects are arranged in a grid-like pattern on the board. 

On the top left, there are three gold-colored rings, one of which appears to be made of metal and the other two are made of brass. On the top right, there is a black rubber o-ring, which is likely used to seal the object in place.

In the center of the board, on the bottom left, is a small black object with a curved shape and a small hole in the center. Next to it is a smaller black object, which could be a part of a larger object. On top of the black object is a label with Chinese characters, which likely provides information about the objects and their purpose.
- There are also two small black buttons on the right side of the image, which may be used to attach the objects to the board or display them.
