~From the HP~

This is a stone flute, the Knob model, made of cute blue jade.
The specifications of the stone flute, which will satisfy everyone from beginners to advanced players, and the three-dimensional design that utilizes the natural form of the raw stone are unique to Nunakawa Jade Studio!

It's only natural that it's evaluated by professional musicians, as it aims for a good tone, ease of playing, a wide range, and a beautiful appearance.
However, we often receive compliments from general customers, not just for its musical performance, but also saying, It feels good just to hold it, so I hold it even when I sleep, or When I'm tired at work, I hide in the restroom and hold the stone flute to feel healed. This is the pride of a craftsman.
In addition to the specifications and appearance of the stone flute, the comfort when holding it is an important factor in developing a fondness for it. If you become attached to it, you will cherish it, and that attachment will lead to a good sound.
We hope you will enjoy a stone flute that cannot be experienced with cheap mass-produced items.
