I have various other items for sale as well. This is a large, thick-shelled *Horagai* (conch shell used in Shugendo). It is approximately 39cm long and weighs 1284g (^.^)♪♪♪❣️ The mouthpiece hole is about 6mm. There are natural growth marks and limestone deposits. There are no cracks. Please check the photos. I have confirmed that the *Horagai* can produce five tones (two *otsu* tones: wood and fire, and three *kō* tones: earth, metal, and water). If you need a beginner's guide to blowing the *Horagai*, please write in the comments section. I will include it for free. Free shipping nationwide! The price may fluctuate depending on the cost of the shell.
