After obtaining the raw material called,
Grenadilla, it is left to air dry for 10 year.
The material then goes through another stringent screening process and only one third of the material finally ends up being formed into a flute.
Created with the careful application of time and energy, the sound, which can be said to be the original sound of the flute, expends a sense of maturity.
The tube is relatively thick at 4.2mm. A selection can be made from three types of mouthpieces.
