EGGBUTT RING gives a horse clear pressure to turn. The ring is fixed to the mouthpiece allowing it to move back and forth. Therefore, EGGBUTT does not rotate like loose ring, preventing it from pinching the lip. Good design to start with young horses. This shaped mouthpiece is very mild and ideal for mouthing young horses. A twisted wire core passes through the centre of the elastic polymer which bows in the direction of pressure. This flexibility sends preliminary signal for the horse to prepare the movement of rein. She can be in relaxed and neutral state. This light weight mouthpiece acts equally on the bars, the tongue, the lips and corner of mouth. This mouthpiece is constricted in the middle with a twisted wire core passing through the centre. The thick 24mm mouthpiece creates space in the middle to keep tongue free. Flexible as Mullen, but more direct pressure on the bars than the tongue. This light weight mouthpiece is suitable for thick tongued horses.
