Teeth cleaning device equipped with 5 modes and an ultrasonic transducer. - Number of Modes: 5 Modes - Ultrasonic Transducer: Ultrasonic Transducer - Vibration Technology: 2 million times/min sonic vibration tech Thank you for viewing. I threw away the main unit's packaging, but it's a new, unused item. I go to the dentist regularly, so I don't have a chance to use it. I'd like to sell it. I bought it on Amazon for 3650 yen!
