6" Cheeks, 5" Mouth. 3/8" Smooth Copper Snaffle Argentine. Very nice bit if your horse has a "good" mouth. Low leverage shanks combined with a medium control mouthpiece. Copper creates a moist soft mouth for better feel. Copper is a soft metal, watch for excessive wear. Stage B is all about transition, with the introduction of leverage and curb pressure. Short shanked bits and half-gags comprise Stage B.
