The Shires Brass Alloy Flat Ring Lozenge Eggbutt Snaffle features fixed rings to prevent pinching and provide a more stable contact with the mouth. It is made from brass alloy, known for being warm and palatable. The double-jointed mouthpiece distributes pressure evenly over both the tongue and the bars of the mouth, encouraging mouthing and contact. Mouthpiece thickness is 13mm, and cheek height is 55mm for sizes 4.5" and 5", and 75mm for sizes 5.5" and 6". The brass alloy mouth is durable and aids salivation. Stainless steel is used for the cheeks, offering durability, ease of cleaning, and rust resistance.
