This is a shakuhachi flute I received from my great-grandfather. I don't know the specific type, so I asked ChatGPT, and I'm using the title it suggested. [Kinko-ryu Shakuhachi, Two-Piece, Split-Type, Rooted, Ji-nashi, Vermilion Mouthpiece, Burned-in Mark] This is based on AI analysis, but I think an analysis by someone knowledgeable about shakuhachi based on the photos would be more accurate, so I've included many photos. Please consider them before purchasing. It's a shakuhachi that comes apart into upper and lower sections. I am a woman, so I don't have much strength, and I was afraid of inserting it too forcefully. Therefore, as shown in the 9th photo, I haven't inserted it all the way into the joint. The mouthpiece has a cap and is clean. The inside is painted red. There appears to be a pink stain on the 6th photo. I believe this is an old item, so please refrain from purchasing if you are overly concerned about its condition.
