Made with a single, three-dimensional molding that offers excellent elasticity and breathability, it gently wraps the chin and facial muscles. It uses soft, skin-friendly, highly elastic fabric for less stress during long periods of wear. Easy to put on, just secure with Velcro at the top of the head and the back of the head. Size is adjustable, so anyone can use it. Highly recommended for those who suffer from snoring and those who experience severe throat pain or dry mouth upon waking. Also, by continuously tightening the facial muscles, a slimming effect can be expected. ※ Start with a loose fixation at first, and gradually tighten it as you get used to it.
