Expertly crafted for equestrian use, the TRUST Leather Dee offers a unique combination of reinforced nylon core and naturally tanned, chemical-free leather. The round construction and flexible leather mouthpiece make this bit ideal for sensitive horses, while mares are particularly drawn to the taste. Regularly applying olive oil will keep the leather supple for long-lasting use. Just remember to make sure the stitching points to the outside for proper positioning.
