Thank you for viewing my item (*^^*) ⭕️ Instant purchase ⭕️ Anonymous shipping ⭕️ Same-day shipping This is a neck massage device that you wear around your neck. It uses EMS (electrical stimulation) and heat to care for your neck. You can adjust the warming function and vibration, making it very comfortable. Recommended for those with severe neck stiffness (*^^*) I've used it a few times, but the one I already have is sufficient, so I'm selling this one. I will clean it thoroughly with alcohol and pack it for shipping. Operation has been confirmed. <Contents> ・Box ・Main unit ・Instruction manual ・Charging cable
