This set includes two medium-size Thadobati cups. Both bowls are approximately 200 years old. Two of these instruments individually are of high quality and could be easily used separately. However, as a set, they create magic patterns that scientifically called "binaural beats". The measurable binaural beats effect is present in this set on SIX levels, but it's far more than the frequency analyzer is refusing to pick!
