The Rubber bit guards are gentle rubber disks that prevent the bit from pinching the corner of your horse's lips. Sold in pairs, one disk for each side of the bit. Push the disk over the bit cheek to place on the bit. Disks will be just outside the horse's mouth as a buffer between his lips and the bit rings. Convenient and simple bit accessory for greater comfort for your horse. Three colors available, Black, Brown, and White. One Size.
