This Myler bit is a stainless steel 3 3/4" Dee with Cyprium Twisted Snaffle (MB 09T) Copper Inlay Mouth. This mouthpiece is made of Cyprium, a nickel-free copper alloy that encourages salivation. The unique mouthpiece is curved so the bars of the bit wrap the horse’s bar and lips instead of pinching. The curve also creates more space for the horse’s tongue under the bit. Like new!
