For easy and worry-free douching, even on the go, this squeeze-bulb style enema system takes care of business. The soft bulb of the CleanStream Premium One-Way Valve Anal Douche is equipped with a one way valve that prevents back-flow. The nozzle is smooth and slender for comfortable insertion. The two pieces disassemble for easy filling and cleaning, and when not in use, the nozzle can be flipped around and stored inside the bulb.
