Panasonic RF Facial Device EH-SR70 This device uses radio waves and ultrasonic waves for skincare, eliminating the need for cotton pads. The device has been disinfected and its functionality has been confirmed. I received this as a gift and used it about 10 times, but it has been stored unused for several years. I will sell this to someone who understands that it is a used item. There are no noticeable scratches, but there is some yellowing and minor scratches. Please check the photos.
