I have various other items for sale. This is a large Tōkamuri conch shell. It's approximately 25cm long and weighs 1338g (^.^)♪ It contains small stones that it incorporated during its growth, so it rattles when shaken, but this doesn't affect the sound at all ^ ^♪♪ I've confirmed that the conch shell can produce a 5-note scale (Oto = 2 notes: wood and fire), (Kō = 3 notes: earth, metal, and water) ^o^♪♪ Especially the low notes (Oto) resonate quite a bit ^ ^♪ *Whoom*♪ Like in the Sengoku period. It's powerful and beautiful, so how about using it as interior decoration? Please take a look at my profile ^ ^♪♪ The mouthpiece hole is about 6.5mm. There are growth marks. There are no cracks. Please check the photos. It's beautiful and has a thick body, so please enjoy the booming Oto sound ♪♪♪ Conch shells of this shape are also used by high school students in taiko drumming clubs and music clubs. If you need a beginner's text on how to play the conch shell, please write in the comment section. I'll include it for free ♪♪♪ The price is determined by the cost of the shell.
