Reinsman Traditional Heavy Loose Ring Snaffle. 3" rings with 5" mouth, 7/1" 3 piece with copper roller.
 
"Traditional rings with more weight for better feel. Mouthpiece breaks over the bars a t a different angle to contact new nerves with some tongue pressure for better control. Mullen relief mouthpiece creates even pressure across the bars and tongue to eliminate nutcracker effect. Copper roller adds moisture and acts as a pacificer. Copper is soft metal, watch for excessive wear."
