Requiring only two minutes a day, this is the exercise apparatus that tones jaw and neck muscles for a thinner and tighter chin. It uses spring resistance—the same method employed in full body exercise equipment—to help eliminate double chins and droopy jowls without the risks or cost of cosmetic surgery. It works by placing the device between your upper chest and chin and moving your jaw up and down in a chewing-like motion or tilting your neck up and down in a nod-like motion. With three interchangeable springs for varying levels of resistance. 6 1/2" L x 2" W x 2" D. (4 oz.)
