This bit has 7 inch cheeks with 5 inch mouth. It is great for horses who respond well to light cues, or for riders who are still learning to quiet their hands. The Ribbon Snaffle falls in between a smooth snaffle and twisted snaffle in aggressiveness. It is a great choice for most horses as it acts most like a smooth snaffle, but has a tad bit more control if needed. Sweet iron naturally rusts into a light patina. The rust creates a sweet taste for the horse, making the bit more acceptable and increasing salivation for a supple mouth. It comes with LIFETIME GUARANTEE from the manufacturer - REINSMAN.
