I have various other items for sale as well. This is a large *shugen-do* conch shell. It's approximately 38.5cm long and weighs 978g (^.^)♪❣️ The mouthpiece hole is about 6mm. There are natural growth marks. There are no cracks. Please check the photos. I've confirmed that the conch shell can produce five tones (two *otsu-on* notes = wood and fire), and (three *ko-on* notes = earth, metal, and water). If you need a beginner's guide to playing the conch shell, please write in the comment section. I will include it for free. Free shipping nationwide❣️ The price may fluctuate depending on the cost of the shell.
