These are swim diapers. They function the same way as disposable paper swim diapers, but can be washed and reused many times (^o^) My twins wore matching swimsuits! As you can see from the name tags in the photos, one has been washed about 10 times, and the other 3 times. There are no noticeable stains or damage♪ Great for spares. (Currently 1 year 8 months old) Perfect for the upcoming season, like heated pools, beaches on overseas trips, and water play in the garden or on the veranda next summer!!
