The One-Way Valve Enema Bulb comes with all the premium characteristics of a standard top-of-the-line enema, with the added bonus that its nozzle features a one-way flow valve to reduce messy backflow. The nozzle is 5 inches long, flexible to allow for easy insertion, and features sideways-pointing holes for effective cleansing and a secure screw-in construction so you won’t have to worry about it coming out of the bulb. 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 Enema Bulb is soft with easy-grip ridges, and measures 5.2” tall with a 1.15” diameter. The included one-way flow nozzle is 5.85” long with a diameter of 0.75”. 10 oz / 300 mL capacity. Made from non-toxic PVC.
