Bombers Polo Eggbutt Gag Snaffle Ultra ComfyThe Bombers Polo Eggbutt Gag will create leverage on the mouthpiece whilst at the same time introducing more poll pressure. The Eggbutt shape will prevent pinching of the lips. The mouthpiece is extra curved, creating a more comfortable bend than the conventional, which reduces pinch and spreads pressure points around the bars and reduces the nutcracker action.
