This is a silver-plated metal cone-shaped wine cup. It has a triangular base and a handle. You can chill it in the refrigerator and pour cold beer into it, which enhances the coolness of the beer, and it can also be used as a beer glass. It only holds a small amount, just enough to drink in one gulp. My father bought it about 40 years ago at the imported tableware section of Yokohama Mitsukoshi. It was stored and displayed in a curio cabinet. - Shape: Cone-shaped - Material: Metal (silver-plated) - Base shape: Triangular - Design: Inverted triangle with a handle
