The Acu Palm is the perfect gift for desk or office workers, artists, chefs, nurses, former athletes, or anyone who needs to care for their hands. It’s the only portable, powerful desktop hand massager that charges via USB and works for up to 3 hours on a single charge. The longer design of the Acu Palm offers an effective heated compression massage that reaches from the fingers to the wrist. The finger “window” allows those with larger/longer hands to fit. The massager works by rhythmically inflating top and bottom airbags that press and release the muscles and joints of the hands, stretching them out and encouraging blood circulation. The inner cloth lining is studded with rubber nodes that stimulate important acupressure points of the palm and fingers, according to the practice of reflexology. The Acu Palm has three strength levels to suit all preferences; three pre-programmed massages to Refresh, Recover, or Relax; heat therapy settings to warm muscles and joints; a cordless design with a rechargeable built-in battery; a USB charger for added portability, and a classic outer shell that will suit even the most discerning tastes.
