Purchased in December 2024 from the official Suncore shop on Rakuten Ichiba. Used for approximately one month during the newborn period for twins, with them lying side-by-side. Regular size futon mattress: 6990 yen Waterproof sheets: 2990 yen x 2 The futon mattress has no damage or stains, as far as a casual inspection can tell. It's difficult to see in the photos, but there is some slight yellowing on parts of the waterproof sheets (photos 7 and 8). There is no damage. All items have been washed at home before listing. However, some lint and small balls of fabric have gotten trapped inside the mesh of the futon mattress cover (photo 4). It was difficult to remove them, so the items will be shipped in this condition. I believe all items can be used without any problems. No smokers, no pets. Will be packaged in a black plastic bag for shipping. Overall, the items are in relatively good condition, but please understand the above points and that these are used items before purchasing.
