This is a tumbler made of authentic "Ryukyu glass," a traditional craft of Okinawa. The vibrant blue and light blue gradation reminiscent of the Okinawan sea, along with the fine bubbles throughout, create a very fantastical and beautiful piece. Each one is made by a craftsman using the glass-blowing technique, so it has a thickness and a handmade warmth. The form fits comfortably in your hand, and it's perfect for drinking awamori, shochu on the rocks, or cold tea. 【Size】 ● Height: Approximately 10.5cm ● Drinking rim diameter: Approximately 6.8cm ※ Please forgive any slight errors as this is amateur measurement. ※ Due to being handmade, there are subtle individual differences. 【Condition】 There are no noticeable cracks or chips, but it has been stored at home for a long time and kept in a display case, so it is being sold as a used item. Please enjoy the unique bubbles and subtle irregularities of Ryukyu glass as proof of its handmade nature. 【Shipping】 It will be carefully wrapped in bubble wrap (protective material) to prevent breakage and shipped in a plastic cylindrical case. (Scheduled to be sent via Rakuraku Mercari Bin or Yu Yu Mercari Bin) This is a wonderful glass that lets you feel the Okinawan breeze. How about it for your evening drinks or relaxation time?
