[b]Sara Titanium Mouthpiece goes with the Otto combination bit. When you order a mouthpiece for your combination bit, please select a size that's 1cm larger. [u]Please understand:[/u] We make the mouthpieces just for you once you order. So, you can't return or exchange them. We create them from our standard loose ring bits to fit your needs.[/b] This lets us give you a variety of mouthpiece options and sizes for your custom bit! [i]Fager Sara is a good choice if you would describe your horse as the following;[/i] * Has difficulty seeking out the contact. * Constantly falls behind the bit * Sticks the tongue out. * Frantically chews at the bit. * A younger horse. * Feels stiff in other standard straight bits.
