These are water play diapers/pants with a marine life pattern. Suitable for: Babies aged 0-3 years old. Great for swimming lessons, parks, the sea, and pool water play. The waterproof outer layer and polyester mesh inner layer are easy to wash and gentle on baby's skin. Adjustable snap buttons allow for a custom fit for toddlers, making them easy to put on and take off. The elastic polyurethane fiber material around the waist and legs not only provides a snug fit but also helps prevent leaks in case of a bowel movement. When used with a shaped diaper pad, they can be used as leak-proof pants or as a diaper cover. Brand new and unused.
