This classic snaffle bit has been the top choice of trainers and riders through the ages.

Traditional Loose Ring with Smooth Copper Snaffle.
4.5 Inch Mouth.  
3 Inch Rings. 
3/8" Smooth Copper Snaffle
Stage A.
The combination of the slightly weighted ring with an average size 3/8" smooth makes it a perfect all around mouth. Copper creates moisture, packs well and keeps well in high salt areas. Copper is a soft metal, watch for excessive wear. Mullen relief mouthpiece creates even pressure across the bars and tongue to eliminate nutcracker effect.
