This is a glass beer mug from the Showa era, like a child's plaything. I believe I obtained it about 12 to 25 years ago at a flea market or antique shop. There are manufacturing burrs on the inside rim of the cup, and there are a few small chips there. The V-shape of the drinking edge is not a chip, but original to the design. There is an "JAPAN" embossed on the bottom. Overall, I think it can be considered a beautiful item. Please check the photos for the detailed condition and size of the product, and make your judgment.
