This non-woven fabric box sheet features a 5-sided waterproof design for peace of mind. - Size: 100 x 200 x 30cm - Waterproofing: 5-sided waterproof - Material: Non-woven fabric - OEKO-TEX certified: Yes The above description was generated by AI. This is a set of two single-size, fully waterproof box sheets. I purchased them last June and used them for about six months. During that time, there were no accidents, and there are no visible stains to the naked eye, but since these are bedding items, please only purchase if you are not concerned. Also, these were not stored specifically for sale, so there are wrinkles. They will be shipped compressed, so expect significant wrinkling. Thank you.
