Adorable Vintage Swivel Panda Bear Pin

Pin is in like new condition with almost no flaws other than very minor surface scratches. Pin has to parts connected together with a gold toned jump ring giving it a slightly movement when worn. Bamboo canopy is used are the pin with a Panda Bear enjoying a lunchtime snack is connect via jump ring. Manufactures marking stamped on reverse but they are in Chinese. I believe this pin was purchased on a trip my mother took to Hong Kong many year ago. I believe CWCA stands for China Wildlife Conservation Association but I could be wrong. See photos for measurements I don't know much else about this brooch as I'm selling it on behalf of another party. I'm also not able to be extremely flexible on offers as I am selling this on behalf of someone else. Questions? Please ask prior to purchase.
