This is a neck and shoulder-warming pillow (Brand: CALQS). It's a hot pillow designed to help you achieve comfortable sleep by warming your neck at 40 degrees for 15 minutes. *It does not have a massage function. It comes with a light gray cover (washed). I've used it about 5 times, and it's in very clean condition. It is a used item, so please refrain from purchasing if you are concerned. There are no instructions or box.
