Happy Mouth Loose Ring Straight Bit apple scented, tough, non-toxic, flexible mouth with reinforcing stainless steel. The loose rings snaffles make a more mobile bit than an eggbutt or fixed cheek bit, which should encourage your horse to keep a relaxed jaw and mouth the bit. The loose ring may be useful if your horse leans on the bit, or takes hold, as the bit is always movable so the horse cannot take hold as easily as they could with a fixed cheek. The Straight bar is a very mild mouthpiece; it is an unvarying mouthpiece, which means the pressure on the mouth doesn't change very much, as it is a fixed mouthpiece. The bit puts pressure on the tongue and lips (corner of the mouth), it does use slight pressure on the bars depending on the size of your horses tongue. This bit is very useful for those horses who have a very soft mouth and don't like complicated mouthpieces, it may also be useful for horses who back off the contact and need that extra bit of confidence in the bit.
