This butt plug has a rubber tube running through it. Fluids can pass through while it is inflated! Once the plug is inserted and inflated the large rubber hose can be hooked to an enema bag. When the time comes to administer the enema, the fluid will flow through the enema butt plug into the colon. The inflatable plug prevents pushing out the plug and the enema until the desired time arrives.
Inflates by means of a bulb with release valve.
The Enema Plug is 4.5 inches long and 1.5 inches wide. When inflated, it widens to a little over 2 inches wide.
