Months were spent perfecting this design so that it has a perfectly rounded tip with no sharp edges to catch sensitive tissue. The unique reverse taper also has benefits, allowing you to hold the nozzle in place if you contract you your anal sphincter. The larger water outlet hole allows for lots of irrigation and the ability to run water through it under a tap for easy cleaning after use. The usable portion of the nozzle is 3.25 long. The nozzle also has the StreemMaster safety ridge, protecting rectal tissue from the threads. Black. Healthcare Grade Silicone, Phthalate and latex free.
