The unique Apple-Scented Mouthpiece encourages horses to accept the bit. Space age polymer provides a gentler bit for a happier horse. Exacting care goes into each bit: All the bit cheeks and rings are made of a top grade stainless steel in the traditional way of lost wax casting. All the bits have a core of special stainless steel for maximum strength. Mouthpieces are non-toxic, soft, flexible and long lasting polyurethane to help protect the horse's teeth. (Bits must be the correct size and correctly fitted for best results). Happy Mouth Horse Bits are favorites with Top Trainers in many disciplines.
