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).
