This Myler bit is perfect for young horses with a steady disposition or older horses just beginning training. Mullen mouthpieces have a gentle outward curve to the mouthpiece, giving even pressure and allowing the tongue more room. They place pressure on the tongue, lips, and bars. The moutpiece is flexible and forgiving when relaxed, solid with tongue pressure when engaged. This mouthpiece will naturally oxidize, or rust. Harmless to horses, it has a sweet taste and promotes salivation. 7inch HBT stainless steel shanks. Myler Level 2 mouthpiece.
