This is the therapy mask that uses targeted vibration massage to help provide pain relief from migraines, headaches, and sinus pain. The device’s integrated nodes vibrate to stimulate blood circulation to help reduce pain, aid in meditation, or help one relax after work or travel. It’s powered by a built-in battery that enables one to wear the device without being tethered to a cord or outlet. Made with cotton, the mask is soft, breathable, and comfortable on the skin. With three levels of massage intensity. Charges via USB; a full charge provides up to 45 minutes of power. Black. One size; adjusts with hook-and-loop fasteners.
