Anello sciolto ferro dolce snaffle cavallo bit con losanga di rame (venditore UK, P&P gratuito)

Loose Ring Sweet Iron Snaffle Bit with Copper Lozenge. The added benefit of a copper lozenge gives a warm feel in the mouth and reduces the nutcracker effect of this bit. The Sweet Iron bit will develop a thin layer of orange/brown rust on the mouthpiece when temporarily not in use.
