TWO RING COPPER LOZENGE GAGWith a stainless steel mouthpiece, this bit is durable, easy to clean, tasteless and does not rust. The addition of a copper link creates warmth and encourages salivation for a soft mouth. Two rings allow for the rein to be placed on either the main ring or smaller lower ring for more leverage. Gag's put pressure on both the bars of the mouth and the poll for increased flexion and lower head carriage.
