This item was purchased nearly 20 years ago during my first trip to Okinawa. The side is stamped with "Pure Silver 99.9" and the designer's name, "NOBU." It has been used many times and has some scratches. Also, although I polished it with a cloth, it will inevitably tarnish when exposed to air because it is pure silver. I plan to polish it again before shipping. This item requires regular care. The glass in the center is light blue. Please use your preferred chain. I will adjust the price at my own discretion, so please understand.
