Online for Equine offer the Cottage Craft Mullen Mouth Eggbutt Snaffle.
This mullen mouth eggbutt snaffle is ideal for horses who dislike the nutcracker action of single jointed bits. Eggbutt sides help keep the bit central in the mouth and prevent rubbing. Designed with a gentle curvature mullen mouths allow more room for the tongue so are useful for horses with large tongues.
Available in widths 4.5, 5 and 5.5".
