The Korsteel Hard Rubber Mouth Loose Ring Snaffle is a fun and mild alternative to a metal mouthpiece. For horses that are sensitive, and even reactive, the mouth, this might be an option. It is also a great bit for colder temperatures, as the rubber will stay much warmer than a metal bit. The hard rubber covers a stainless steel single-jointed mouthpiece. The hard rubber is more durable than the soft, which will offer the 'spongy' feel, without being as vulnerable to the teeth. This bit is great for horses that have had previous biting issues and now need to regain trust. It can also be a bit to keep around in for horses recovering from dental issues, as the rubber lays very comfortably against the bars of the horse's mouth. The loose rings show off the beautiful stainless steel outer parts. The freedom of movement as the rings slide through the drilled holes on the mouthpiece. This allows the horse to have a little 'play' with the bit. The play discourages a horse from leaning on the bit. The stable construction of inner part of the bit makes it durable. The stainless steel rings are hand polished and non-corrosive. It is easy to clean and easy to maintain.
