This is bubble glass made by Moriyoshi Inamine, a leading figure in Ryukyu glass. The color is a simple and popular clear. Impurities in the discarded bottles create bubbles, producing a beautiful appearance. Moriyoshi Inamine's Ryukyu glass is very popular, but he has already passed away, and new pieces, including our stock, are rarely available, even on the main island of Okinawa. Please consider this valuable work by Moriyoshi Inamine. We are an authorized dealer. We only handle authentic items, so please purchase with confidence.
