I'm including a ME Beautique and an eye-area-specific facial device. There is a socket, but the cord has writing on it (see photo). Other than the cord, there are no noticeable stains. Both devices can be used with this cord. The compact facial device is equipped with thermal and EMS functions. The other one is an EMS device specifically for the eye area. - Set includes: Facial device body, charger - Functions: Massage function, thermal function, EMS - Operation buttons: 3 operation buttons (intensity adjustment, mode switching) - Size: Compact design, easy to hold I have used it a few times. If you were interested, how about it? Thank you for looking.
