Nomisk Luna Massager Neck and Lower Back (helps soothe cramps) Luna uses heat and pulse therapy to mimic a massage. This helps relieve neck pain by relaxing tight muscles and promoting blood flow to deliver the right nutrients to the region. In turn, this improves neck mobility and reduces stress and headaches. It features various massage modes and intensities to choose from, it's also lightweight and rechargeable —so you can take it anywhere. It’s preowned but only used once or twice. Almost brand new. The charger for the neck is missing but there is a charger in the back pad one.
