Professional Equine Western DRing Comfort Snaffle Bit is a nice bit for horses just starting out and learning the basics. This bit applies tongue and bar pressure and uses restraining and releasing action. The curved mouthpiece allows horses to swallow freely. This bit has stainless steel Western Dees and a copper inlaid soft iron mouthpiece and a copper roller. Copper naturally promotes salivation and increases sensitivity within the mouth. Mouth Size: 5.5"
