A high quality and original creation, the Koshi Chime is an authentic musical instrument...played by the wind. (But yes, you can certainly use your hand to get out the magnificent tones inside as well.)
Handcrafted with precision at the foot of the Pyrenees, Koshi Chimes are designed with eight notes. The notes are metal pieces welded into a plate at the base of the resonating tube. The tube itself is made of thin layers of bamboo veneer treated with natural oils. The veneer is stronger than natural bamboo and makes for a much sturdier chime, without losing the acoustic qualities bamboo is famous for.
PLEASE NOTE: Koshi Chimes can be used for all kinds of sound events and placed in so many locations. (Maybe not interstellar emptiness, where one ends up questioning the design of the physical universe, as you note the light years between crystal charging stations, but pretty much everywhere else.)
Cheer Up and Chime Up, Citizens of Earth. It's going to be fun when the Intergalactic Freeway comes through this Solar System!
