This is a Thousand Leaves Alto C-tube A-type ocarina. Thousand Leaves ocarinas are made in a workshop in Chiba Prefecture. The ocarinas are crafted by Mr. Minoru Chiba, who is also an ocarina player. The sound produced by his unique and beautiful ocarinas is truly exquisite. I purchased this at Ocarina House, but I am selling it because I will not be using it. Thank you.
