These are the therapeutic gloves that vibrate to help stimulate blood flow in the fingers and provide drug-free relief from pain and stiffness. With slim nodes strategically placed over each finger and thumb joint, the gloves provide a gentle vibration that helps massage away pain and improve flexibility. This comfortable movement, combined with a slight compression exerted by the gloves' slim fit, creates a soothing warmth that helps enhance circulation and ease soreness. The soft gloves are made from a breathable blend of 92% cotton/8% spandex, and they facilitate a firm grip with textured undersides, which are subtly printed with positive messages to help combat the psychological strain of living with pain. Each glove provides up to 20 minutes of treatment after a four-hour charge with the included AC adapter. Wipe clean with a damp cloth. Black. One Pair. Unisex sizes S, M, and L. (3 oz.)
