No more reasons - no more excuses: "I don't have much money", "I don't have time to go to the gym". Whether at work, the gym, at home or on the go, you can use the trainer anywhere. Get great results in just 10 minutes a day Beautiful packaging - Each pack contains 6 pieces of chin exercise pieces and 6 pieces of beautiful storage boxes and 6 pieces of straps HIGH QUALITY MATERIAL - The double chin trainer is made of food-grade silicone. Non-toxic silicone does not contain any chemical fillers or by-products, so you can chew with confidence. Jaw training balls are made from the same material as baby pacifiers. Before first use, place product in boiling water for 15 to 20 seconds Humanized Design - The film jawline training ball is designed to use molars for exercises, which is safer and more effective. Unlike other types of exercisers that use incisions in the incisors for training, other types of exercisers can damage the incisors and gums Multiple Benefits Chewing has been shown to reduce appetite, leading to further weight loss and the elimination of double chins and flabby facial muscles. Chin trainers strengthen your chin and face, making your face firmer, more jagged, and slimmer, making you look younger. Rinse with warm water after use and keep dry for next use
