The snaffle bit creates direct pressure without leverage on the mouth.  The mouthpiece of the bit acts on the tongue and bars of the mouth (severity depends on the style) and the sides of the jawbone.  The loose rings allow the bit to move around within the horse's mouth, which encourages further softening and mouthing.  When the rein aids are relaxed it allows the Loose Ring to distribute immediate release and relief from tongue and bar pressure, as the bit is immediately reset to a neutral position in the horse's mouth thus rewarding a correct response.

The Pingguo mouth bits are made from a polyurethane material, which is light, and flexible, they are suitable for use on a young horse, sensitive horses, horses just backed or those horses who are not comfortable in conventional stainless steel bits.
