This is a Ryukyu glass wine glass. My parents collected these over 20 years ago when they were single, and they've been sitting in the china cabinet at my parents' house, so I'm putting them up for sale. They were hardly used at my parents' house, but there may be some minor signs of use and scratches. I will clean them to some extent, but please be aware of this if you are particularly concerned about such things. I will wrap them in cushioning material for packaging. [Notes] This is a single red glass for sale. (Image 1) The other glasses in the second image are listed separately, but you can also purchase them as a set, so please inquire.
