YILIMZ 3PCS Jaw Trainer With 3 Resistance Levels - Silicone Exerciser for Men & Women, Activating Tightening Strengthening Facial Muscles, Jawline Workout and Face Exerciser

New structural upgrade: The upgraded jaw trainer can reduce the pressure on your cheeks caused by vacuum during training. This jawline exerciser can better fit the mouth and teeth, improving the training stability during jaw training. During jaw movement, the tongue needs to move backwards to tighten the jaw tissue, reducing contact between the tongue and the product, and reducing the amount of saliva produced by the tongue. Shark shaped jaw exerciser: Shark jaw, made of food grade silicone, with 3 resistance levels, red 40 pounds, blue 50 pounds, and black 60 pounds. The U-shaped face exerciser can make jaw exercise easier. Whether you are a beginner in chin training or have experience using jawline exerciser, this chin trainer will not disappoint you. Professional design: Based on the shape of a shark, it tilts from the inside out, consistent with the height of the teeth during biting, so that the biting force of the teeth is evenly distributed on each resistance arm, connecting the entire facial muscles. The design of the jaw trainer has anti vacuum holes throughout the entire structure, allowing for quick rebound after biting teeth without sucking on the mouth. Equipped with cleaning tools: Our jaw trainer is easy to clean. Just use toothpaste and a tube brush for deep, dead angle cleaning, and you can safely reuse the chin trainer. Each jawline shaper is packaged in a separate transparent box for easy portability. Lifetime Service: Our jaw trainer comes with a lifetime warranty! Customer satisfaction is our top priority! If you encounter any problems with our chin trainer or want to return it for any reason, we will handle it as soon as possible！
