Used about 4 times. I'm selling it because it didn't personally suit me and it takes up more space than I expected. This is the MYTREX electric neck stretcher, which has both heating and EMS functions. Purchased online in September 2025. I've discarded the box, so it will be shipped with protective packaging. - Product Name: MYTREX MEDI NECK - Purchase Price: ¥24,750 - Functions: Heating, EMS, Traction Thank you for looking.
