Thank you for viewing. I purchased this for my child, but I don't remember when. I used this waterproof sheet under the regular bed sheet. I haven't used it for a while and have been storing it in a storage case. I'm selling it because I won't be using it anymore. Size: 100 x 210 cm Single futon size. There is a small stain on one sheet. Please see the photos. I didn't find any other issues, but please understand that this is a personal inspection. I do not have any pets, and I do not smoke. Shipping will be in simple packaging. Thank you for your understanding. I hope that those who understand that this is a used item that has been stored at home will purchase it.
