Acupuncture Finger Massager silver plated 1pc. You can use it to roll on your fingers if you need to throw off the sleepiness, or a tired "is it still just 2 o'clock?" feeling, before a long drive, anytime you need to stay alert. Acupuncture and reflexology have their wonderful uses, and this ring in particular. Do not wear the ring for a long period of time, just roll it on every finger. Can be used to fight stress, as a fidget.
