This is a bedwetting sheet (waterproof sheet). It has rubber bands on all four corners to prevent slipping, and it's washable. I opened it and pre-washed it, but it's unused. There are some fold wrinkles from storage. Size: 60cm x 90cm I will fold it up small and compress it for shipping. Instant purchase is OK, but please read the profile before purchasing m(_ _)m #PreschoolPreparation
