This is a glass from UMIKAZE, a Ryukyu glass studio in Yomitan Village, Okinawa Prefecture. The clear glass, with its intricate combination of blue and bubbles at the bottom, gives the impression of capturing the beautiful sea of Okinawa. I've used it for about six months, so there are some fine scratches if you look closely, but it's in good condition. (Images from the 7th photo onwards are reference images) Diameter is about 7cm, height is about 8.5cm. I'm selling it due to downsizing for a move. Thank you.
