Total length: 55cm. The name "Kosui" is written on it. I tried blowing it, and it seems to produce sound, but I have no knowledge of the shakuhachi, so I don't know anything about the tone, adjustments, etc. I will disinfect it thoroughly with high-concentration alcohol before shipping, but please refrain from purchasing if you are concerned (⁎ᴗ͈ˬᴗ͈⁎) Although there are no major scratches or stains, I don't know what it originally was, so I've marked it as "has scratches and stains." Since it is a used item, please refrain from purchasing if you are concerned about minor details (⁎ᴗ͈ˬᴗ͈⁎)
