The Korsteel JP Flexi Bits are made from hi-tech plastic which has been moulded around a core of stainless steel. The flexi mouthpiece is `warmer` than a traditional stainless steel mouthpiece. Flexi mouthpieces are a good choice for younger horses and those with a sensitive mouth. The main action of the Oval Link Snaffle is on the tongue and the bars of the mouth. The central link drastically reduces the nutcracker action associated with single joint bits, which can cause horses to raise their heads to evade the bit. This bit is suitable for a horse or pony who is just starting their ridden career or for horses with sensitive mouths. This bit is dressage legal. Plastic should be checked before every use for sharp edges where the horse may have chewed the mouthpiece. Ref: UTWB370
