Please watch the video so you can hear it, regular and current mantra chanting boxes are priced between $40 and $70, since this one is vintage and RARE the price increases. It works, it only has one setting although there are three turns that the last knob will do so I’m not sure if there were other chants and it doesn’t work or what that button really does. There was one crack in the plastic on the front but otherwise in good condition. Would be nice for a prayer room or as background music during a ceremony, please ask any questions and if you have any more information feel free to comment! Reasonable offers will be accepted.
