Lalabye Baby Wet/Dry Bags are made of stretchy, waterproof TPU and have a handle with a durable snap closure. Just snap it around your wrist, stroller or diaper bag for an outing with baby. The flat bottom allows the bag to stand on its own and makes it easy to pack. The Just in Case Wet/Dry Bagfits about 2 diapers, but can also be used for diapering accessories, toiletries, mama cloth, anything! The bags are easy to clean - just throw them in the washing machine with the dirty diapers or other laundry.
