With the power of 25,000 ultrasonic vibrations per minute, it supports skin cleansing/water peeling, penetration/introduction, and lifting. I used it about three times, but I gave up after three days, so it's been in the drawer. Operation has been confirmed. Items to be sent: 〇 Main unit 〇 USB cord (unused) 〇 Instruction manual 〇 Outer box Since it has been used, I would like to request purchase from those who understand.
