This is an extremely rare Infinity Ocarina AC pipe. It was a miraculous collaboration ocarina jointly developed by the now-defunct Mr. Chimura's "Phantom Pecorino Ocarina" and the Korean Jin Ocarina, produced by Mr. Miru. This ocarina will never be made again. It is a very easy-to-handle AC pipe with a wonderful resonance, making it ideal for solo performances. Although it has some minor scratches due to its age, it is perfect for both practical use and collection. Please consider it.
