This is a conch shell made under the supervision of a Yamabushi (mountain ascetic) chief priest. Set of 3, with a whistle. You can blow it and it makes a sound, but it's a small one. It doesn't produce a sound as loud as a conch shell from the Sengoku period (Warring States period). The taper of the mouthpiece has been deeply cut and a 6mm pipe has been inserted, making it relatively easy to produce a sound. Attach the whistle and it transforms into a shell flute! How about using it as a bear whistle for mountain climbing! Regarding the production, it has been thoroughly cleaned, disinfected, and processed, but it is a natural product. Please refrain from purchasing if you are sensitive or seek perfection. Regarding transactions, no claims and no returns are accepted. It is also listed on other sites, so please understand that it will be removed from sale once sold out.
