[High quality material] The exerciser is made of free food grade silicone. Non-toxic silica gel does not contain any chemical fillers or by-products, so you can chew with confidence. It is made of the same material as the baby pacifier.
[Humanized design] The exercise film is designed to use molars for training, which is safer and more effective. Different from other types of exercisers, using front teeth (incisions) for training, this exerciser may damage the front teeth and gums.
[Multiple benefits] Chewing has been proven to reduce cravings, leading to more weight loss, getting rid of double chin and loose facial muscles. The jaw trainer strengthens your jaw and face to help tighten, jagged and slim your face, making you look younger.
[No more reason] There are no more excuses: "I don't have a lot of money", "I don't have time to go to the gym". Whether you are at work, fitness, at home or on the road, you can use the double chin reducer anywhere.
