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 Korsteel JP Flexi Jointed Dutch Gag Two Ring bits main action is on the horses poll, the roof of the mouth and on the bars of the mouth. The amount of poll pressure can be increased by attaching the rein to the bottom ring, making the bit stronger and more severe. The Two Ring Dutch Gag can be used with one rein, two reins or with roundings. This bit is not dressage legal. Plastic should be checked before every use for sharp edges where the horse may have chewed the mouthpiece. Ref: UTWB345
