I purchased 3 sets of these “Best of the Best” bowls from a private collection while travelling in Nepal. I have 2 complete sets and one more which I have been selling separate. This beauty is one of the separates. Best of the Best is an 8 pieces set made for sound and vibration from the finest of metals combined by expert hands and finished into a luscious smooth as silk sound that penetrates the body to heal and sooth. This bowl would be the perfect addition to any doing sound therapy or enjoys the magic of sound. It vibrates at A# I have 2 complete sets and one more which I have been selling separate.
