This Black KinkLab Speculum is a medical tool for investigating body cavities.
Just like the ones used by obstetric and gynecologist. These speculum is the bi valved vaginal specula; the two blades are hinged and are closed when the speculum is inserted to facilitate its entry and opened in its final position where they can be arrested by a screw mechanism, so that the operator is freed from keeping the blades apart. From Kink Lab, The Speculum is for all your medical role play.
