Retro glass cup, glass Purchased at an antique market. It has a substantial feel because it's glass. It also has a handle, making it easy to use. I fell in love with the unique design, but I haven't used it much after buying it, and it's been stored in the cupboard. It's not completely unused, as I got it at an antique market. There are no obvious scratches or damage. Showa retro tableware Retro glass, glass cup
