This product is a vintage brass belt from Taiwan with Chinese cultural influences. The belt is 40 inches long and features a 3.5 x 5 inch character for "luck". It is unclear what the ownership history of the belt is. The belt is not handmade and is likely a mass-produced item.
The belt has a large "key" at the end as you can see from the photos. The belt was probably a wall hanging made into a belt. The hook is in good shape.
Please see photos.
