This is a facial device from Nitori☆ You can switch the temperature of the massage head between "HOT" and "COOL", and also switch to EMS mode. HOT mode: Heats up to about 40°C and vibrates. COOL mode: Cools down to about 16°C. EMS mode: Stimulates the skin with a microcurrent. I received it as a gift and haven't used it, but it seems to have good reviews☆ The retail price is around 5000 yen. I have a similar one, so I'm offering it to someone who wants it (^o^) Care... Lift-up, Warm/Moisturize Area... Face Features... EMS
