Reinsman junior cow horse smooth single joint, PONY bit. 5" cheeks, 3 1/2" mouth. 3/8" single joint mouthpiece.
 
"It helps to get your horse's legs underneath him and his rear end down. The short gag action collects a horse very well. The snaffle mouthpiece is our most popular and is light enough to pull young colts around without damaging their mouth."
