Product Id: To-89-21043 — The Mb 04 Is Similar To The Mb 02 In That It Will Rotate On The Tongue And Apply Tongue Pressure, However, It Has A Small (¼”) Port That Introduces Some Tongue Relief To The Horse. The Port Allows The Horse To Swallow And Move His Tongue When He Is Moving Forward And Relaxed, Which Acts As A Release Or Reward. The Mouthpiece Is Curved, And It Wraps Around The Bars And Lips Instead Of Pinching.
