The popular happy tongue design features a solid mouthpiece that is uniquely ported to give maximum tongue relief. This is curved to be soft on the bars and slow in applying tongue pressure.
Made from a blue sweet iron, it oxidises easily which encourages salivation and encourages acceptance.
The 2.5 ring eggbutt gag side prevents pinching of the lips and give a slightly more solid feel against the side of the face. It also prevents the bit being pulled through the mouth.
Lightly used and in good condition. Sweet iron has oxidised but this is normal.
