Shires Blue Sweet Iron Loose Ring Snaffle Bit with Lozenge can discourage fixing and leaning as it has much more movement than a fixed cheek to follow the angle of the tongue. The shaped lozenge offers even pressure and encourages mouthing and contact. Stainless steel is the most common material type for bits. Durable, easy to clean, tasteless and it does not rust. Blue sweet iron oxidises easily to create warmth and a sweet taste which helps with bit acceptance and encourages salivation. The addition of Brass Alloy inserts help produce a warm, more palatable bit.
