The One-Way Valve Anal Douche comes with all the premium characteristics of a standard top-of-the-line douche bulb, with the added bonus that its nozzle features a one-way flow valve to reduce messy backflow. The nozzle is 3 inches long, thin and sturdy for easy insertion. Best of all, the nozzle is designed so that liquid can only flow out of the bulb, not in, which reduces backflow to make the process more sanitary and make cleanup easy. The bulb is easy to clean with warm water and antibacterial soap. The One-Way Valve Anal Douche is soft and easy to grip, and measures 4.1” tall with a 0.8” diameter. The included one-way flow nozzle is 2.8” long with a diameter of 0.2”. 7.5 oz / 225 mL capacity. Made from non-toxic PVC.
