This is an unused, multi-functional massager. I bought it but never used it, so I'm selling it. When used for shoulder massage, you can place it on your back to massage your neck and shoulder blades. It can also massage your lower back, thighs, and calves. The box is slightly crushed, but I will package the outside for shipping. I have confirmed that it works. A charger and a car adapter are included. Thank you.
