A good proctoscope allows you to open and look at the anal and rectal cavities. Our proctoscopes are thorough medical instruments that are very safe to use. The hollow channel (the part that looks like a funnel) can be used to insert other objects, besides the included light component. You can inject air or water through the channel or any other anal toys. For those interested in a little fantasy in the doctor's office would enjoy having this item in their bag of tricks.
