Stocking brands such as Neue Schule, Eldonian, Sprenger as well as many others Houghton Country offer a wide range of mouthpieces in the Eggbutt snaffle design.
Eggbutt snaffles are widely used for a variety of disciples and minimise two problems which can occur with a loose ring snaffle, the fixed rings prevent pinching at the edges of the horse's mouth and provide a more stable mouthpiece which is useful if your horse plays with the bit.
