Now a Jennings Mouth Gag with a soft rubber coating over the metal mouth piece and a buckling neck strap for holding it in place. This deluxe model is much more comfortable then the standard all-metal one.

This piece can be adjusted from comfortable to painful, depending on how far open you press the levers that gradually open these two rubber coated metal bars. They won't be able to close their mouth in the slightest once this device is lodged in behind their teeth. Imagine what you can then do to them while in this position.

This is a medical grade Jennings mouth gag.

Having a hard time keeping their mouth wide open? Well, with this fine piece of German engineering that won't be a problem in the slightest!
