This is a Sankyo flute. It is handmade and made of solid silver (there is a 925 stamp). It is old but has been used very little. There are polishing scratches. There are no dents or damage from impact. The case has small scratches. I purchased it about 30 years ago and have taken good care of it. The case also appears to be embossed real leather. It feels soft and familiar when you hold it. It used to have a leather scent, but that is no longer present. It was very expensive even at the time, and similar models seem to have increased in price even further now. Would you be interested? Regarding the serial number, the teacher who acted as an intermediary worked very hard to get a nice, round number. I believe that adds value as well. Due to the high price, we cannot accept returns to prevent issues such as swapping. Please consider carefully before purchasing. It comes with a black cleaning rod that looks like carbon.
