This medical device is used by dentists and oral surgeons to keep mouths open during examinations and surgeries. Made of high quality polished stainless steel. Measures 5.5 inches from end to end. Widest setting is 2.5 inches.
Highly recommended. Very clean looking, secure and effective. Relatively comfortable to wear, while keeping the mouth wide open for unobstructive access, especially for more intense play such as mouth-soaping, cigarette-ash tipping, etc.
