I bought this when I visited Minamata City, as they were making environmentally friendly products. It's a cup made from recycled glass. The word "Hakutake" is written on the bottom, so I think it was made from a liquor bottle. It's new and unused. If anyone is interested, please let me know. Diameter: Approximately 8cm Height: Approximately 7.5cm I have three of them, so please let me know if you'd like one.
