5 _" Cheeks, 5 _" Mouth. The Just Enough is a very nice transition bit when moving from the ring snaffle to a curb bit. The limited gag action is softer than moving from the ring snaffle directly into a curb bit with swivel or solid cheeks. The 3-piece ergonomically designed mouthpiece results in soft and even pressure across the tongue, bars and lips. Reinsman's Sweet & Sour mouthpiece tastes like a green apple dipped in molasses and is sure to become your horse's favorite! The sweet and sour combination causes increased salivation, leading to a more relaxed jaw and a supple mouth. Copper is a soft metal, check for signs of wear before each use.
