This is an octagonal underwater flower shift knob (octagonal shift knob). Because of its angular head, the flower is beautifully reflected in the head of the main body. It has been cleaned. The length is approximately 14.6cm, although this is a rough measurement. The screw size is M12 x 1.25, I believe. How about using it in an old car, or as a vintage collection or interior item? It will be carefully packaged and shipped via Yu-Yu Mercari delivery service.
