The arched mouthpiece of this bit curves upwards instead of outwards like a mullen, however the action is quite similar. The rein can be used on either loop, depending on the severity of rein action required for the horse. 

This bit comes complete with a leather curb strap for improved comfort to the horse. It features finer dimensions to suit small ponies
