Loose ring Stubben snaffle has a 5" mouth. Stainless steel with a sweet copper dogbone or lozenge.
Stubben is one of the finest makers of bits and tack.
There is no nutcracker effect, giving even balanced pressure on the tongue and bars but no palate pressure. This makes this bit more forgiving in inexperienced or strong handed riders. The loose rings gives the horse the most flexibility to place the bit where it's most comfortable in his mouth. Great for young horses learning how to carry a bit.
