A jaw exerciser is a compact device made of silicone or rubber that helps strengthen and tone the muscles in the jaw, face, and neck. By biting down on it with gentle pressure, users engage their jaw muscles, promoting improved jawline definition, reduced tension, and enhanced facial symmetry. It's portable, easy to use, and serves as a non-invasive alternative to cosmetic procedures for achieving a sculpted jawline.

Came very well packaged, and with box. But very hard, buy the weakest one first as a begginer.
