Each piece is individually hand-carved and handcrafted. Coconut and bamboo are used to make these instruments of nature. In addition, musicians hand-tune each chime. Testing the sound of each tube, our musicians/craftsmen create chimes that sound as good as they look. By hand-toning each tube and selecting a range of sizes, they ensure that each chime will produce a unique melody. This product is handcrafted with pride by artisans in Bali, therefore sizes can vary.
