The eggbutt rings on this bit prevent pinching while the EquiKind mullen mouth is mild. The ripples on the mouthpiece add a little pressure for extra control, whilst the apple flavour makes it very palatable. Mouthpiece thickness: 18mm. Cheek height: 70mm. The EquiKind mouthpiece has the benefit of being lighter and more flexible. Particularly suitable for young, sensitive horses as they are kind on the mouth. The apple flavour makes them palatable and therefore easily accepted. Stainless steel is used due to it being durable, easy to clean and resistance to rust.
