This is a waterproof mattress pad for baby bedding from PUPPAPUPO. I used it until about 3 years ago. It's the type that secures with elastic at the four corners, with a towel-like material on the front and a waterproof material on the back. There are two pads: one with a thin beige color and a cherry pattern, and the other with a white background and a star pattern. Both sizes are 70x120cm. There are no noticeable stains, but since they are used items and have been stored by a private individual, I think there is a feeling of use. There may be some minor stains if you look closely. Please understand this before purchasing. There are wrinkles due to storage, but I think they will disappear if you wash them before use. I used these to prevent spit-up and urine leaks when my baby was young. How about them for a change of sheets?
