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 ball 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 zipper bags. We take hygiene seriously 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 compressed area. #UmbilicalHernia #BellyButtonHernia #UmbilicalHernia #Treatment #Baby #Infant #OutieBellyButton #CottonBall #WaterproofSheet
