Spring Loaded Mouth Gag A unique toy to add to your collection. Simply squeeze the ends together and insert the stoppers behind the teeth. As the mouth of the wearer opens, the gag expands and cannot be closed again. If they are unable to keep quiet, they will end up with a wide open mouth and you will have complete control of all things oral. Great for medical play or those with oral fixations. To remove the gag, just press down on the rear portion of the gag and it will release the spring-loaded pressure. Measurements: Expands up to 3 inches. Material: Stainless steel with plastic stoppers. Measurements: 80mm in overall length and 67mm in width. This product is certified 100% Non-Magnate and medical-grade steel. Beware of cheaper products that are not solid surgical steel but chromed steel or poor quality surgical steel that contains Magnate. Magnate is the ingredient that makes steel rust. We will only include this endorsement on our 100% surgical steel products.
