Reinsman Black Tie Dee- 3" rings, 5" mouth. 3 piece Sweet & Sour mouthpiece with even pull. 
 
"This is Reinsman's premier dee ring with no-pinch ball design. The Even Pull element results in soft and even pressure across the tongue, bars and lips and it removes the potential nut-cracker effect of a regular jointed snaffle. Reinsman's sweet and sour mouthpiece increases salivation for a more supple mouth. Copper is a soft metal, check for signs of wear before each use."
