I have various other items for sale as well. This is a mini-mini conch shell. It's a fun item! ^ ^♪ The length is about 18cm and the weight is 153g. It produces both Otsu-on and Kou-on (low and high tones). ♪^o^♪♪❣️ Please take a look at my profile. ^ ^♪♪ The mouthpiece hole is about 6mm. There are natural growth marks. There are no cracks. Please check the photos. The sound is produced in the same way as a Shugendo conch shell. If you need a beginner's text on how to blow the conch shell, please write in the comment section. I will include it for free! ♪♪ The cost of the shells is high, so this is the price.
