The Clean Steam Inflatable Enema Plug has a rubber tube running through it, which allows fluids to pass through while it’s inflated. The rubber hose can be hooked to an enema bag once the plug is inserted. What happens is the fluid will come through the enema butt plug and into the colon. It inflates using a bulb with release valve. This is an effective enema plug and it widens by 2 inches when inflated.
