Fixed rings prevent pinching whilst the lozenge disperses the contact across the mouth to lighten the pressure applied to the tongue. Mouthpiece thickness: 14mm. Cheek height: 55mm (4.5", 5.5"), 75mm (5.5", 6"). Stainless steel is the most common material for bits. Durable, easy to clean, tasteless and does not rust.
