These liners have been very useful, whether used after a bath before bed or during potty training. I liked them so much that I bought a lot and have been storing them. They are unopened, but as shown in image 5, the packaging is slightly creased. I have been storing them at home since around 2023, so I would like to sell them to someone who doesn't mind. Quoted from the following site: By setting one liner in a pull-up diaper, you can save on the number of diapers used. If your child pees, you only need to remove the liner instead of changing the entire diaper. Changing diapers is also easy when you're out and about. ● Soft surface material The part of the sheet that touches the skin is soft and gentle. ● Quick-dry zone Quickly absorbs and prevents leaks. ● Anti-slip tape Five anti-slip tapes fit the liner perfectly to the diaper. ● Smart shape The smart shape fits snugly into the diaper. ● Breathable sheet Fully breathable sheet that prevents stuffiness. ● Soft gathers Soft gathers gently support the legs.
