As shown in the attached image, I am selling an unopened Nishiki Nurse waterproof sheet (pocket type). Material: 100% polyester (knitted fabric with polyurethane film coating) Total weight: Approximately 462g / Dimensions when unfolded: Width: Approximately 90cm × Length: Approximately 180cm The four sides are bag-shaped, designed to wrap and secure the futon. It is unopened and should be perfectly functional, but as it has been stored indoors for a long time, there may be some discoloration or aging of the fabric. (Please refrain from purchasing if you expect a perfect condition, including the appearance, like those found in stores, or if you need it urgently.) The image on the screen may look different from the actual product, so please consider the attached image as a reference. I will answer your questions as best as I can, and in the unlikely event of any defects, I will promptly process a return. However, I kindly ask that the buyer dispose of the item.
