Ten'ya-teki (Special Edition) 2 shaku 1 sun tube. Made by Mr. Ten'ya Takeda (Hiroshima Prefecture). * (Special Edition) is the highest grade of Shinobue flute. This is a valuable Shinobue flute that is no longer made. It's like a side-blown flute version of a shakuhachi. It's a Shinobue flute with a back hole like a Misato flute, so it's recommended to play it with a slight (Meri-fuki) technique. There is a wind hole at the end of the tube. There are no cracks in the tube. There is some light wear and tear, but we appreciate your understanding. We will clean, waterproof, and take shock-resistant measures before shipping. If you have any other questions, please comment. Thank you for your consideration.
