This is a mattress cover for a queen-size bed. From the manufacturer's official website: Approximately 203cm x 152cm x 43cm Protects the mattress from dust mites, dirt, and dust, and is dehumidifying and waterproof. For details, please check the AlleEase official website (English). It is also sold on Amazon (approximately 15,000 yen), but it appears to be imported from overseas (excluding customs duties?). I purchased this several years ago and tried to use it, but the size didn't fit, so I folded it and stored it for a long time. Although it is unused, when I unfolded it, I found some stains like those in the image, possibly because it was stored in the closet without being put in a bag. In addition, there are some surface fuzz and slight wrinkles, but there is no significant damage that would obviously make it undesirable to use, even to the untrained eye. However, although I have carefully inspected it, there is a possibility that I have overlooked minor stains or other minor damage that is not very noticeable. Individual perceptions inevitably vary, so please purchase only if you can accept and understand all of these points.
