Thank you for viewing. This is a Keratta waterproof sheet. [From Rakuten product details] - Dryer-safe - 90 x 170cm - Wrap-around type I purchased it on Rakuten in May 2022 for caregiving purposes and used it occasionally for six months. After that, it was stored in a closet drawer. I used several waterproof sheets in rotation, placing them under regular mattress pads, so there is some slight fraying, but there are no noticeable stains, and I think it can still be used. (Please check the photos) I hope you will understand that this is a used item and has been stored by a private individual before purchasing. Instant purchase is OK.
