Thank you for viewing. This is a "Umbilical Hernia Compression Care Set for 10 Uses" that can be used to care for a baby's umbilical hernia (commonly known as "outie belly button"). This product is perfect for those who feel it's wasteful to buy a large quantity of commercially available materials. The set includes items equivalent to those prescribed in hospitals for umbilical hernias: 10 clean cotton balls (approximately 3cm in diameter) used in medical settings, and 10 sheets of skin-friendly waterproof film. By replacing the cotton balls and waterproof film every 1-2 days, you can maintain a clean condition and minimize skin problems and the risk of infection. Especially since these items come into direct contact with a baby's delicate skin, being disposable is an important point. The cotton balls and waterproof film are individually packaged in zippered bags. We take hygiene into consideration and will send the items in a waterproof package and envelope. Please discontinue use immediately if you notice any redness, rash, or discomfort in the compression area. #UmbilicalHernia #BellyButtonHernia #UmbilicalHernia #Treatment #Baby #Infant #OutieBellyButton #CottonBall #WaterproofSheet
