Korsteel's Copper Roller Mouth Eggbutt Snaffle Bit has a 5" mouth. Made with a copper roller, this bit causes a horse's mouth to salivate. This allows the mouth to stay soft and useable to the rider. An eggbutt snaffle bit is named for the shape of its ring and is designed to prevent pinching of the horse's mouth. | Korsteel Copper Roller Mouth Eggbutt Snaffle Bit | Size 5"
