This is a singing bowl set from amanamana in Nishi-Azabu, Tokyo. I purchased it about two years ago after visiting the store and listening to the sound many times. Although I haven't used it very often, there is some clouding on the main body due to long-term storage, and the stick has some white spots. In my personal opinion, the sound is as beautiful as when I first bought it. The warranty is not included. The set is also for sale. Retail price: 49,280 yen Size: Approximately 21.3cm
