The Three Fork Metal Anal Speculum goes one step further than its two forked counterpart. It not only allows the anus to be prised apart width ways but also lengthways so that the anal opening can potentially be opened further. Simply insert the speculum, squeeze the hand grips and tighten to the appropriate level with the adjustable screws. This speculum is also easy to keep clean as it is made from stainless steel. NB. The forks measure 3.5 inches long.
