Hiromichi Ocarina SF Key (Soprano has 13 holes) Purchased about a year ago and used only a few times. It produces sound with little breath, making it very easy to play. And it has a resonant, beautiful tone. I have several, so I'm putting this one up for sale. Please take a look at the photos and only purchase if you understand. This is a reliable ocarina, so returns are not accepted. Thank you. (The ease of playing high notes is particularly impressive, and with the Hiromichi Ocarina, you can play the high notes "Re, Mi, Fa" with a clear, transparent sound even without tilting the ocarina, just by blowing at an easy angle. - "Ocarina House")
