Reinsman Medium Loose Ring Sweet & Sour dogbone- 3" rings, 5" mouth.
 
"Multi-use bit designed for all disciplines and any level of horse. The 3-piece ergonomic mouthpiece results in soft, even pressure across the tongue, bars and lips. Sweet & Sour mouthpiece tastes like a green apple dipped in molasses. The combination causes increased salivation to lead to a more relaxed jaw and supple mouth. Copper is a soft metal, check for signs of wear before each use."
