Shires Copper Lozenge Snaffle with Raised Rib BitWe love this Shires Copper Lozenge Snaffle with Raised Rib Bit because it's made with sweet iron and copper. With a sweet iron mouthpiece designed to produce a sweet taste and encourage salivation as it oxidizes. The addition of copper ribs helps to prevent the horse from taking too much contact, a good deterrent for horses that tend to take hold. The copper lozenge and loose ring cheeks make this a relatively mild training bit. Sweet Iron Copper ribs
