loose ring copper coated rollers

Stainless steel with copper roll. 

The copper rollers allow a better relaxation of the horse.

The Magic System bits were developed by Nelson and Rodrigo Pessoa. The main feature of these bits is that you cannot fold these bits in half as far as a normal mouthpiece can. As a result, the bit adapts better to the horse's mouth and there is less pressure on the tongue and palate. This form stimulates swallowing and saliva formation. This makes the horse more able to relax the jaw.

The bits with copper in the mouthpiece promote chewing on the bit, producing saliva and provide a softer and more relaxed mouth for the horse.
