A. Anti-backflow technology: Unlike some other enema nozzles without check valves, this nozzle kit comes with 2 disposable locking valves, which can help prevent the backflow of dirty water. This may allow for a deeper cleaning of the colon or anus for a potentially healthier lifestyle. B. Ergonomic design: The slender nozzle is easy to insert. It has a comfortable grip and can hold about 150 ml of water. The nozzle and the spray head are detachable for easier cleaning and quicker drying. C. Five water spray holes: The nozzle has 5 water spray holes for relatively uniform water spraying. After inserting the specially surface-treated nozzle, squeezing the water-filled silicone bottle by hand can conduct a 360-degree cleaning, which may ensure a relatively deep cleaning of the colon or anus. D. Skin-friendly and safe materials: The outer layer of the nozzle is made of medical-grade silicone that is kind to the body. It is safe, non-toxic, odorless, and free of latex and bisphenol A. It is recommended to use it with a lubricant for a more comfortable experience. E. Bring health and pleasure: Regular cleaning may contribute to the physical care and health of you and your family. It is suitable for both men and women. It may help to eliminate odors, relieve constipation, promote defecation, and cleanse the intestines. It may also help to get rid of bacterial infections and maintain good health. F. This product is packed in a discreet package, so you don't have to worry too much about privacy issues.
